LUFTGRAV #38493C Prototype Luftwaffe Gravity Knife FKm Type II b - SMF

Most of us are familiar with Gravity Knives having the standard and take-down variants equipped with single retractable blade, but most likely few of us are aware of a prototype produced by the SMF firm having a double-edged blade with center ridge. The blade would indicate the new design was being considered for close-combat usage as opposed to the traditional Fallsfirmjäger role of assisting with tangled parachute lines. According to the author of the "Luftwaffe Gravity Knife" reference, Mack A. Pattarozzi, a telegram exists from the OKH directing commanders of specific units to evaluate the "Fliegerkappmesser" in a combat environment and reply within 30 days with the results of their evaluation. No documentation exists as to the results, but a number of these knives were produced, supposedly 900. An example of the Model FKm appears on the cover the Pattarozzi reference book.

I have been in this hobby and business a long time and have bought and sold large quantities of Gravity Knives over the years; this is the first example of the model "FKm" that I have encountered. This example definitely shows usage and apparently was one of the test examples. The mounts of the knife are all in a standard blue finish appearing identical to any other example on the outside. It is interesting that the marlin spike is not waffenamted, since this was not a Luftwaffe or Army issue piece. The mounts all have a good blue finish and the springs are nice and tight. The throat area has the arrow designation, as does the flat bracket below. The activator lever is numbered "51" and the butt of the throat is numbered "10". Just as is often the case in standard pieces, the numbers do not match. The grip plates are the standard walnut wood and they are in fine condition, showing normal darkening caused by handling.

But the important thing here is the blade. It is the same length as a standard Gravity Knife. It differs though, in that there is a distinct center ridge with double edges. The ricasso is tapered downward from the center ridge. The blade edges each have some minor period sharpening. The SMF logo is etched on the reverse ricasso being the seated king holding an upward-pointing sword. Below the "Solingen" etching is the word, "INOX", which is the term used internationally for "Rosfrei", or stainless steel. Other than the edge sharpening, this blade remains in mint condition still having all of its factory grain remaining.

This is an opportunity for the serious Gravity Knife collector to acquire the "holy grail" piece. How many of these were made is a mystery and how many survived the war is unknown. One thing is for sure, it is an extremely rare bird. I know it's a lot of money for a Gravity Knife, but then again, find another!

Excellent Plus. $7,495.00

LUFTGRAV #37708 Takedown Gravity Knife with Army Markings

This Takedown Gravity Knife is in great condition, having 100% bluing to the throat, the activator lever and marlin-spike. The bluing only shows traces of wear on a few of the edges.

The activator lever is marked with a “0” stamping, as well as “1624”. Taking the throat piece off the same number, “1624”, is seen stamped on the bottom butt portion. This number is also stamped on the lower half of the knife visible when it is opened up. The throat has the usual directional arrows, a symbol also seen on the plate below the throat.

The matching blued marlin-spike retains the original tip. In the corner it is property marked “RV 0/0651/0019”. It is very interesting to note that on the reverse of the spike corner is the letter “S”. This letter is the marking used for Army property. Since this knife does not have a Luftwaffe waffenamt and instead has an Army property stamping I believe this knife would have been used by Army paratroopers. Kind of a rare thing here.

The blade of this example remains nice and bright and retains much of the original grain. There is evidence of some edge sharpening but it is not bad.

An excellent Gravity Knife here, with the added bonus of the Army stampings.

LUFTGRAV #37706 Luftwaffe Gravity Knife – Malsch & Ambronn

This Gravity Knife is the first I can recall seeing from Malsch & Ambronn, and should really appeal to those of you who enjoy tracking down seldom seen makers. This example will make a great addition to your collection of rarities.

This piece should usage on the outside, but the nickel-plated parts are still in fine condition. I notice that there are no numbers on the activator lever, or any of the other components for that matter. It is also interesting to note that the spring on this example is constructed from a single piece of steel, as most of the others we see have two individual strips of spring steel. Quite interesting indeed for those who study the construction of these knives.

The marlin-spike is in fairly good condition, the corner being marked with a waffenamt. This mark is hard to see. It appears to be obscured by either grinding or tool marks; it is hard to say for sure. You really have to look closely to see this mark to begin with.

The grip plates are a dark color walnut with a nice, slim feel to them. They appear to be a bit thinner than those we see from Weyersberg and SMF.

The blade is still bright throughout but it does have some sharpening, but nothing too bad. We removed most of it from the obverse side, but didn't restore the reverse as to preserve the trademark. This mark is a bit vague from age but is unmistakable, in the form of a man working an old-fashioned water pump. The name of the town “Steinbach” appears below.

A very interesting Gravity Knife here that is still in good, collectible condition and with a rare maker that is bound to amaze your friends.

Excellent. $995.00(#060616)

LUFTGRAV #29798 Luftwaffe Gravity Knife - SMF

This Luftwaffe Gravity Knife is in good overall condition, having nickel fittings throughout. The nickel is in good shape, the throat fitting having the original owner’s initial “A” scratched into both sides of it. The blade release activator is numbered “2”, as well as “655”. The marlin spike is in good shape and is waffenamt with the stick bird having a “5” in his belly. The grip plates of this example are a good dark walnut and they have a pleasing grain, showing some minor usage signs.

The blade is as good as you will ever see. This mint condition example has full original graining and precise shape. A beautiful example here! The reverse ricasso is darkly etched with the seated king trademark. The king holds an upward pointed sword, while sitting on the firm’s initials, “S.M.F.”. Beneath this in an arch shape is the town, “Solingen”, and beneath this the German word for stainless steel, “Rostfrei”.

A very nice gravity knife here, with good working springs.


LUFTGRAV #28979 Luftwafffe Gravity Knife – SMF

This Luftwaffe Gravity Knife is made of all polished nickel parts and it is the non-takedown type. All of the nickel parts are in good condition throughout. The springs are nice and tight on both the marlin spike and blade. The activator is stamped with a number one and also, “54” underneath this number. The marlin spike has the usual stick bird waffen amt in the lower corner and the bird has a, “5” in his belly. The grip plates are a good oak solid wood and the reverse plate is in good condition throughout. The obverse plate has a gauge cut across the letter portion of the wood as well as a matching type cut across the upper area of the same grip. I do not know why this was done but a lot of things can happen during wartime and perhaps boredom.

The blade of this example works well and it is still bright. It also has quite a bit of crossgraining in the finish. Unfortunately, someone has done a sharpening job and the sharpening was not done too well as some of it has scored the blade itself. It is not bad though and this blade still rates at excellent to excellent plus. In fact, some of this could be taken out if somebody wanted to work with it. All in all though, a good original gravity knife.

Excellent Plus, Plus. $750.00

LUFTGRAV #32872 Luftwaffe Gravity Knife - SMF

This Luftwaffe Gravity Knife appears to have been a nickel-plated version, but possibly, it was produced later in the war as the mounts are a steel base. The mounts are all in good condition, however, there is a light coating of rust that is noticeable on the throat area as well as on the back strap and some area around the marlinspike. It gives the gravity knife an unusual look, as the flush mount four rivets on each side of the throat area stand out against the dark background created by the toned metal base. The springs on both the activator lever and the marlinspike are strong and work nicely. The activator lever is marked “318”. The marlinspike appears to have the original tip and it is waffenamt in the corner.

The grip plates of this example are a fine toned oak and they are in perfect condition, showing very little wear. The blade of this example, on the obverse, is bright and in mint condition with full grain. The reverse of the blade also is still quite nice, although there are some sharpening scars that show about ¾ of the way down. Other than these scars, the reverse blade is still in fine condition also. This blade is etched with the SMF logo that features the seated king holding an upward pointing sword. Below the king are the firm’s initials, “SMF”, and the location town of “Solingen”. Below this is the German word for stainless steel, “Rostfrei”. A nice gravity knife here that with a little effort could have the finish brought up, but actually I kind of like it the way it is. The choice would be up to the next purchaser, as I’m quite sure this finish would clean up.

Excellent. $750.00

LUFTGRAV #34295C Luftwaffe Gravity Knife - F. & A. Helbig

This maker mark for a Gravity Knife is extremely difficult to find. I have sold a lot of gravity knives over the years, and I have only had one F. & A. Helbig example in the past. If there is someone out there that is specializing in gravity knife types, this example should be of prime interest.

Holding the knife next to the Weyersberg and SMF entries, it is interesting to note that the mounts are of a slightly different shape. The throat is different, as is the activator lever and also the grip plates are of a flatter nature than the other types. These aspects all make for a unique item here. The mounts are all nickel plated type, and they are in good shape throughout. There are no number stampings anywhere on this gravity knife. The activator lever spring works well, as does the marlinspike spring. I note also that the marlinspike appears thicker than the types used by the other makers. This marlinspike is stamped on the corner with a waffenamt. The waffenamt is the standard stick bird with a "5" in his belly. The grip plates appear to be walnut, but as stated above, they are flatter in nature than the more curved types used by other producers. These grip plates are in excellent condition throughout, having no flaws or problems.

The blade of this piece unfortunately has some fairly good edge sharpening. The sharpening does go up slightly also into the blade surfaces. In the areas not scarred by the sharpening though, the blade is still factory bright and has all of its crossgraining. The maker mark is very lightly etched on the reverse ricasso, being a double oval. The ovals contain the firm's name "F & A Helbig" and their location below. About half of the maker mark has been worn off by the sharpening. Below the maker mark is the word for stainless steel "ROSTRFEI". An interesting example here, in good working order, and a very rarely seen maker.

Excellent. $1,395.00
