I have a set of Bladetech Stainless Steel runners for Tuuk Lightspeed Edge holders for sale, size 263. I bought these, had them sharpened (5/8"), and skated on them for warm ups before a game and then took them off because I didn't care for the way they felt. They come in their original package, my loss is your gain.
Asking $80 USD shipped in the US, to Canada I will have to calculate shipping so figure a few extra dollars.

These are the stainless steel version not the black coated ones.
