Gary Cain Posted March 15, 2009 Share #1 Posted March 15, 2009 Thought I would share this with the membership as I had not seen one(heard of them just never seen one)till today. It is a very well made private purchase knife made by the William Langbein & Bros. Company of New York. I believe the scabbard to be the original but have no way of knowing for sure. It is made from a single piece of bar stock. Cheers Gary Link to comment Share on other sites More sharing options...

bayonetman Posted March 15, 2009 Share #3 Posted March 15, 2009 The scabbard is similar to the one shown in Cole Book 4, page 152 although Mr. Cole states that the leather scabbard on the one he shows is olive drab. Depending on how the color was achieved, it may be possible that yours has had the color worn off? Very nice find, by the way. Link to comment Share on other sites More sharing options...
nuke41 Posted March 16, 2009 Share #4 Posted March 16, 2009 It is made from a single piece of bar stock. I thought the grip on these was cast to tang aluminum, but I dont have one myself. If its all steel the grip will of course be magnetic if you want to check. Cheers, Jeb Link to comment Share on other sites More sharing options...
Gary Cain Posted March 16, 2009 Author Share #5 Posted March 16, 2009 Hi Jeb, Not if it's made of stainless steel! This one isn't of course but there are those who don't know that. Cheers Gary I thought the grip on these was cast to tang aluminum, but I dont have one myself. If its all steel the grip will of course be magnetic if you want to check.

QED4 Posted March 16, 2009 Share #6 Posted March 16, 2009 Stainless steel is made with iron and a magnet will stick to it. Link to comment Share on other sites More sharing options...
Plant#4 Posted March 16, 2009 Share #7 Posted March 16, 2009 Stainless steel is made with iron and a magnet will stick to it. A magnet will not stick (not very well, anyway ) to high grade stainless steel. Link to comment Share on other sites More sharing options...
QED4 Posted March 16, 2009 Share #8 Posted March 16, 2009 Stainless Steel, like all steel is a alloy of different metals, the stainless parts comes from the higher content of chromium which dose not rust or stain but it is soft, the higher the chromium content the more resistant to rust it is but the softer it is. Stainless steel knives will not take or hold an edge as well as a high carbon steel knife so it is a trade off not having it rust and not holding an edge. Cutlery grade stainless will hold a magnet just fine, if you see a knife that won't don't buy it because you will be sharpening it constantly. How ever there are a few knives made that won't hold a magnet, but they are made to be used in explosive atmospheres and don't give off sparks, again a trade off no sparks for no edge. The stainless you see in trim items like jewelry and car dashboards probably won't hold a magnet because they are going for looks not hardness. This is why a lot of cooks prefer carbon steel knives to stainless because they would rather clean them than sharpen them. But to make a long story short get a good quality stainless knife (there is probably one in your kitchen) and put a magnet on it, I bet you will find it will hold.

Gary Cain Posted March 16, 2009 Author Share #9 Posted March 16, 2009 This is true except for the Austenetic(I think the spelling is correct) Group of Stainless steels(which is what I mostly work with). The 300 series will show very little to no magnetism unless they have been cold worked and when annealed they will return to a non magnetic state.

thebladeslinger Posted March 16, 2009 Share #10 Posted March 16, 2009 Looks like a very nice knife:) I've seen a couple over the last couple of years, but it does seem to be fairly rare. Link to comment Share on other sites More sharing options...
mikedon Posted March 13, 2017 Share #11 Posted March 13, 2017 Langbein was a professional tool maker who specialized in surgical instruments before WWII. When the war started he began making fighting knives to supply US troops on a very limited, one at a time, custom basis. One of the most unusual things about the Langbein knife is that the blade and grip are made of a single piece of tool steel. This type of construction was used in making scalpels and the like to prevent microbes forming in joinst, etc. Another feature of these knives is that Mr. Langbein usually put the name of the owner right on the grip. A couple more examples: Link to comment Share on other sites More sharing options...

Horseclover Posted October 5, 2018 Share #14 Posted October 5, 2018 Martensitic stainless steel (400 series)is magnetic in both annealed and hardened state https://www.azom.com/article.aspx?ArticleID=1141 http://www.spiusa.com/stainlesssteel_overview.php Generally speaking, 300 series stainless is not hardened to martensitic by heat treating but can become somewhat magnetic (and martensitic) in a cold working (ie drop forging) but all 400 series steel will be magnetic. http://auskogroup.com/the-magnet-test-for-stainless-steel-is-not-accurate/ A knife blade that does not stick to a magnet will be comparably very soft. If the above blade is one billet, there is little doubt it is some form of martensitic steel. Tool steels like A2 are air hardened but are also a martensitic steel with more, or less chromium. https://www.paulo.com/s7-d2-a2-difference-tool-steel-properties/ Cheers GC Link to comment Share on other sites More sharing options...
