I never lay a chisel to a build unless it is sharp enough to shave my arm hair ...without a scratch on my arm!
Using a chisel like that is effortless....if all of a sudden the chisel feels different ....you need to strop it again! If for some reason you hit a metal surface ( like inletting a trigger guard and hit the trigger plate...no matter how gently ....you need to sharpen & strop it again! Saves a lot of aggravation, but adds about 1/2 hour to your work!
