Review on DMT DMT20001 BRK Sonic Sharp Straight Hunting Knives by Eric Nallamothu

So I bought one of these from Sportsman stock and gave it rest. The device itself will vibrate to let you know it's doing something. but when pierced with a knife it seems to do nothing. Don't be fooled, with the potential for a professional hand-sharpened job, this is the easiest and quickest shave-worthy job I've found. I hate those spinning deathstones.
