This is a new blade I'm playing with! The grip on this blade is UNREAL! It's quite rough now, I'll show more as I clean it up! What do you guys think? Edited by sybo

Sorry guys, hand finished it up and off it went to heat treat without measurements. Ill get pics and more when it gets back!

The sreel is in a "softer" state when we grind the blades. After the desired shape or profile has been achieved, it is hand finished to the desired finish. The blade at that point can be sharpened but will not "hold" an edge. At that point the steel (depending on the type) is heated to a high temp for a specific length of time and then "quenched" in a liquid such as oil and then sometimes cryoed down to 300 degrees below zero. After a few tweaks the target hardness is achieved by changing the "grain" of the steel leaving it much harder and tougher to make a blade that will hold an edge much better! Hope this answers your question! Jim

Ignorant to what heat treatment means. CAn you give me a a brief.

I'd like to expand if I may. Steel that is cooled slowly is made up entirely of auestinte. This is acehvived by heating the steel to critical temperature, for most simple carbon steels this is 1475 degrees. You then stick it in ashes, sand, etc so it will cool at a slow rate. This makes it soft and easy to grind, and relieves stress if you are forging. After shaping you do heat treat, which for a simple steel like 1084 means you heat it to 1475, checking with a magbet. When it goes non-magnetic it is at critical temperature, you pull it out of the fire and quickly quench it in oil, or brine. This hardens the steel by transforming it to marstenite. It is super hard, but also very brittle. It would hold an edge forever, but it will shatter if you tap it on an anvil. So to get the brittleness out of it, you heat it in an over to 400 degrees or you use a forge. An oven makes it all the same temper. Using a forge, I can make the back soft by heating it hotter, taking out more brittleness. This makes a tougher knife with good edge retention. Sorry if I sounded long winded, and I hope I didn't step on your toes Sybo.

Finally got around to finish this cool little knife. 3 1/2" blade, 8" overall, CPM 154 steel, hardened to 60 with G-10 scales and deco and brass pins. Strategic scallops on the grip makes the hand lock in the perfect position for hard use! A bit of decorative file work and light Jimping dress it up a bit. It is available and will be listed in the gear classifieds!!
