Tonight I was showing my bro in law some features that Doug recommended on knives, learned from reading here. The knife is a Masters of Defense CQD Mark II. I was showing the finger guard when, like a complete fool, I ran my finger right over it onto the serrated portion cutting my finger pretty deeply just above the last knuckle on my right index finger. I knew I wanted a physician to evaluate it. Luckily, it only needed medical superglue to close and not stitches. Be careful with those knives.
