Should have, according to my doctor friend. A moment of carelessness while wiping the blade could have earned me another 4-5 stitches to my credit. Cut the finger smooth to the bone. But, I hate visiting the ER because of the co-pay and hellish wait. So, I grabbed a tube of superglue and went to work. It's what my friend does at his MMA gym does when they have a little too much contact during training sessions. Works like a champ.
