What does it it take to be a good cutman? It's more a question of how bad a cutman can be when you consider what a cutman can do in the 45-50 seconds he has to work on the cut. The first thing is to quickly wipe the blood away with a slightly damp cloth. You don't want excess moisture thinning the blood and making it more difficult to coagulate. Then the cutman has a cotton swab ready saturated in a solution of adrenaline 1000 to 1 although I believe there are a couple more formulas that are allowed and used these days. They are all designed to do the same job of coagulating the blood thereby stopping the flow of blood. The cut man then places the swab in the cut and pinches the extremities of the cut onto the swab and holds pressure until he hears the seconds out call. He then takes the swab away and smears the cut with vaseline. So there is not much more a cutman can do. Problems come when cut men stray from this process. Take a look at the Linares De marco fight where cutman Jesus Chavez kept taking the swab away to admire his handy work for the incorrect way of treating a cut. Pressure must be held on the cut for as long as possible. Linares might have won that fight with a better cutman.
You talkin' like you some kind of professional, so why you asking us what it would take to be a good cutman?
Who does the OP think is a good cutman? I remember Ricky Hatton had a lot of praise for his cutman Mick Williamson. I think he's a cabbie by day if I remember correctly.
