Nakano,
THe CAMPANION edge bevel is spec'd between 30-35 degrees. Keep in mind that they are all hand sharpened, so some variance is to be expected. My personal sample CAMPANION measured 33 degrees when I got it. IT also tends to get a little thicker at the tip.
Other BK&T models... The TACTOOL is different because its a chisel grind, and I don't remember off the top of my head what it is.
The CAMPANION, BRUTE, and MACHAX are all spec'd the same, but the BRUTE and MACHAX both get considerably thicher at the tip for reinforcment.
The MAGNUM CAMP KNIFE is of thinner stock and higher grind....I'll have to check, but I believe that they spec. it at 25-30 degrees.
But remember, they are all HAND SHARPENED. THe good folks in the sharpening dept worry more about sharpness than exact # of degrees.
I hope this helps, and thanks for the interest...enjoy your CAMPANION!
