Here is a 5.5" Chef with Cocobolo scales and a very thin 1095 with a differentially hardened blade!
I did some destructive tests with a couple knives with this steel and heat treat and found that I could go a bit thinner if I wanted to than my standard .010" behind the edge. I took one down to an incredibly thin .003" behind the edge, and flexed it over a brass rod set up sitting on a scale to see just how much force that thin of an edge would take, and it was incredible!! At .003" behind the edge laying the blade against the brass rod at a 30 degree angle it took less than 5 pounds of force to flex the edge. then increasing the force the edge flexed beautifully until at 30 pounds, the edge cracked! that's right, it cracked, but did not chip! the crack went from the very cutting edge, to the shoulder and then stopped! the test was simply amazing! I still like .010 for a standard, but for those that like them extra thin, this is great news!
This one is .008" behind the edge! bear in mind, that my old straight razor is .005" behind the edge!
OAL- 9 1/2"
blade- 5 3/8" long, .062" thick at the spine, and .008" thick behind the edge at the heel. 1 3/4" wide
steel- 1095 high carbon, differentially hardened. heat treat includes a double normalize, double anneal, double edge quench { about half of the blades width} and triple temper for a really nice performing blade that takes and holds a great edge and yet is easy to resharpen!
grind- a full flat grind, sharpened on a Norton Fine India stone with micro bevels, to an agressive razor edge
finish- 220 grit finish under a scotchbrite belt finish, with light firescale finish on the spine,
handle- Cocobolo scales, with Brass corby bolts. handle is finished with 200 grit with the lines running across the handle so it looks good yet isn't slick
sheath- no sheath on this one, but I can make one if needed for an extra $20.
I haven't come up with a standard of tests for kitchen knives yet, but I did test this one out on a 1/2" manila rope that I use on my hunters. this is very coarse and abrasive rope that is very hard on an edge. this knife went 101 cuts on the rope before it required a 2 pound gain in force to complete each cut. the first cut required 14 pounds, and the 101th cut took 16 pounds on my cutting board scale {14 pounds includes the weight of the cutting board, the rope, and the weight of my hand to hold the rope}. It also passed several edge flexes on the brass rod test. she fell through carrots and potatoes, cut straight to the board, with very little pressure, Im going to have to make me one of these now!
the prototype of this knife design did very close to the same in cutting performance, and then after we cooked lunch with it to check performance in the kitchen, we cut more rope, did 12 edge flexes on each side with no chipping or rolling, and then clamped her in a vise and she did 4- 90 degree flexes { 2 in each direction, I cant tell how many foot pounds of torque were required as my torque wrench is set for narrow tang hunters and couldn't attach it to the handle} without breaking or the edge cracking. after the last flex, I straightened her out, and plan to put a handle on her and use her for a new leather knife.
