The interest shown in knife esoterica (high end steels, grind varieties, etc.) is fascinating. I, of course, are not affected by any of this at all, but as an archaeologist, I have a deep professional commitment to understanding this most fundamental and basic tool, whose origins go back eons...
That is why I only own about thirty or so, not counting all my multitools. Most are pretty nondescript steel, but I have a couple fashioned from 154-CM and D2 (for me, at least, those are high end steels).
But seriously, what do you gain from an expensive blade that isn't present in a $15 Mora or in any of several Buck knives with well heat treated stainless steel (I have carried and used a Buck 105 since the early 70s and it still works quite well).
I am wondering about obtaining a kukri or similar to go with my vintage Collins machete, strictly to expand my knowledge.
Thank heavens I am not a knife knut, and my interest is STRICTLY professional ...Just for the record, I am a real fan of the RSK Mk5, owning at least three....
