1095 high carbon steel vs. 7Cr17 stainless steel

Postby scout1 » Thu Dec 13, 2012 10:25 pm

I'm wanting to learn a little more about knife steel and would like any opinions or information I can get back. I'm trying to compair 2 Schrade brand fixed blade "survival" knifes. The SCHF3N looks like a great knife with Micarta handles and 7Cr17 high carbon stainless steel. The SCHF9 also looks very nice with a thick blade made of 1095 high carbon steel. Both knifes are around $35 on Amazon and ebay. Good price on either but I would like any input on what might be better steel.

You want a steel that is a good mix of hardness so it holds an edge, and toughness so it isn't so brittle as to chip and break easily under hard use, an accidental drop, etc. Glass can be terribly sharp but a glass knife blade wouldn't last 10 seconds in actual use. Rockwell hardness of about 58 is generally considered good, which is a function of the steel and proper heat treating. 440C stainless is considered good for knives and has .95% carbon. 1095 also has .95% carbon and is very hard for a sharp edge, and is a well respected steel. The 7Cr17 appears to have a carbon content of .12%, much less than 1095 and 44C, and equivalent to 430 stainless, which is inferior to 440C. Based solely on the named steel it looks like the 1095 would be able to hold a better edge. That's what the charts say anyway, actual mileage may vary, offer void in Alaska and Hawaii. Though I haven't purchased a Schrade for 20+ years, they have a decent reputation, I have several Schrade folders that have made a lot of little sticks out of big sticks, still going strong.

Thanks for the great info Argus. I think the 1095 high carbon steel is the way to go even tho it can rust. I take care of my knifes so that should be no problem. The Schrade Extreme Survival SCHF9 looks like a good knife espically for the price. Not that I "need" another knife tho since I already have about the same type of knife (a SOG Fixation) and recently added a K-Bar Becker BK2 to my collection. Man I just love collecting cool knifes tho!

Wiping your knives down with a tuf-cloth can prevent any rust problems that you might see with 1095 steel.

1095 high carbon steel is nice although it needs a monitor furnishing to avoid rusty problems...
