I'm looking to get my first regrind done by Tom Krein, and I'm wondering what you would suggest as to the knife and the grind? I was thinking about getting a Spyderco Centofante IV reground with a very thin primary grind and a 10 degree inclusive secondary bevel, just so I can have an incredibly sharp cutter. Not for EDC necessarily, just something to have that's extremely sharp. Also, I've been looking at some less common knives, and was thinking about getting a Kanetsune Yama fixed blade reground with, once again, a high, thin primary grind and a 10 degree inclusive bevel. What would you suggest?
