Guitar Picks

This is a 1.85 minute video response from Matt Hammond on Nov 1st, 2008

Question:

"Hakkabuff says ,"Hi, my name is Guomundur and I'm from Iceland. My friends call me Gummi (but I know it's hard for non Icelanders to pronounce so I've been called Gummie in non Icelandic communities). Anyway my question is about guitar picks. I have a problem with my fingernails, they tend to be very brittle and break very easily and I remember seeing a guitarist use metal picks that strap onto the fingers. My question is this: Are those kind of picks custom made or can I buy them from a store, and if they're not custom made are there multiple brands out there? My local shops don't have any and they don't have any info on them. My fingernails can break even if I apply pressure on the pads of my fingers. (this condition affects me only in the winter time, genetics what a bore, eh?)""
