  1. Looking up "Epic" in the encyclopedia should display this knife by default!
  2. Nice one Faye - work looks clean and tidy. Only critique i can come up with, is that maybe the last 2/3's of the handle looks slightly bulky, compared to the elegant lines on blade&bolster, but it might just be the pictures. I really like it.
  3. Enters Forum - drops mic. Well done sir
  4. Jerrod: The data sheet uses both names 135cr3 & 130CrV3 respectively - composition from the French supplier as follows:
  5. Hi Joel & Jerrod, Thanks for posting. I always get the terminology wrong reg. Heat treatment, no news there (but kindly noted) I sadly don't have any proper heat treatment oven, nor IR-thermometer - so my low tech approach is bring the blade to non-magnetic in my gasforge in a dimly lit Room, and compare to a color chart. The i use that "look-up" as a point of visual reference/baseline. You're probably right that my lack of accurate temperature control is the root cause. I just never had this issue before, on approx. 50 blades in misc. steels, but maybe chrome+vanadium is exposing my poor method more clearly, than the "simpler" steel i normally use? Is there a resonably affordable way to measure blade temperature accurately (sub 150 USD if possible)? Ohh, forget to mention that i use holding time of 5 minutes at quenching temperatur, for a 3mm / 1/8" thick blade. Thx again for taking the time.
  6. Hi, I am working with some New steel, and have issues with very coarse grain structure. The steel is european grade 130 CrV3 (close to w2). I did 3 x normalizing, starting at just over unmagnetic on the first run, and just below unmagnetic at the last one. All three cycles allowed to air cool. Quench at approx 820 deg. C in parks 50, preheated to about 40 deg. C. Tempered 2 x 1 hrs at 230 deg. C. Had a small warp, and tried straightning in a vise, straight after last anneal (still warm). Snapped very loudly, and revealed a super course grain in the fracture. I normally use steels like 1075CR, UHB20C, 1080CrV2 and 52100, but never had this happen before. What went wrong? Tips & hints appreciated. Kind regards, Mikkel
  7. Beautiful work - you have every reason to be proud and pleased with your effort...
