so after months of shaving I spent a good 2 hours realy slowly and carefuly touching up my edge on a chinese 12k. It was beautiful. it was like shaving right after I got it. and of course I was relaxing and enjoying a wonderful shave when my hand shook and I embeded the blade right into my thumbnail. luckily it was well above the level of the flesh, effectively clipping my nail, but now I can acttualy see the deflection in the cutting edge. 2 hours gone. and now I need to reset a bevel.

I love trials by fire. what was your best/worst "Of course..." moment?
