kneading hammers

[David Boyce]

You know, the more I think about voicing using Vise-Grips rather than 
pliers, the less I like it.  I see the logic that once it's set up, the 
pressure applied to each hammer is theoretically the same.  BUT, I think it 
would be all too easy to accidentally drop it while attached to the hammer 
felt, or catch it on a sleeve, or in some other way do something that might 
almost rip the felt off the hammer.(or the hammer head off the shank) 
because the Grip is gripping it!
Plus, the hammers may not all require the same pressure anyway.  It sounds 
safer and maybe speedier to me to proceed cautiously with a not-too-huge 
pair of pliers.

Best,

David.
