Review (3/5): Needs re-grinding and adjustment to cut properly
While the straight blade is razor sharp, the teeth side has a 90 degree grind no wonder people are saying it doesn't cut. I didn't feel like returning, so I grinded the teethed side to a 45 degree angle, then honed the final edge (Took 40 minutes total). It comes with an adjustment tool, so turn the adjusting screw alot tighter. NOW it cuts hair like butter. I like the larger chunks it removes. Probably 35% thinning rate, AKA removes 35% of hair.
