I'm going to sound like an old popular member on here and say "I have been shooting deer for 40 years never measured my bevel"..............I have read where Some say if it's too thin the edge will roll, to thick it wont get razor sharp....Well there is plenty of hunters on here using 3 blades ( snuffers, woodmans,etc) and they are flat grinding at best 45 degrees angle...They'll fight you if you say their heads aren't sharp......then theres the single bevel crowd thats pushing what 16-19 degree stuff and they split bones with this low angle
...........Long story short.....if you can get a burr on 1 side of blade about size of human hair and flip it back and forth till it flakes off.....thens it's razor sticky sharp and will definitely smoke through 18" of deer mass.....it's what ever angle you can get Razor sticky sharp will work just fine.
