steel question

[Rande 0]

hi there.

i want to buy new steel for my tacks with the original holder (ccm e pro, i guess) and i dont know which size it is.

I got a size in 8, is this the same size of steel as a 7.5 skate has ?

I planning to change the skate from a 8 to a 7.5, so that i can put the used from the size 8 under the new size 7.5 skate

thanks so far.
