Boot stretching (ball and ring) pliers: wholesale

[gru...@yahoo.com]

(Yes, I already tried posting at The Crispin Colloquy)

I know this is a bit off-topic, but I'm looking for a manufacturer,
distributer or other quantity discount source for a tool variously
called:

1. ball and ring pliers
2. hoke and ball pliers
3. leather stretching pliers
4. shoe [or boot] stretcher
5. shoe [or boot] stretching pliers
6. bunion stretcher

It is a locking jaw pliers or clamp with a spherical ball on one side
and a
ring on the other, used to spot stretch
leather shoes and boots.

There are several retail price sources, ranging from $22-$50, such as

Does anyone know a wholesale, manufacturer or quantity discount
source?

Application: I want to produce a kit to modify boot (e.g., skate) fit.
