Swa cutter

[BlueToBits]

Since this thread last had an airing I had another go with the Kewtec cutter. After a couple of failed attempts I had a close look at the blade and noticed the teeth were the wrong way round.
I pulled the blade out of the plastic disc with a pair of pliers and lo, it's just a 20mm length of Junior hacksaw blade wedged in to the holder. I imagine that the official replacement blades are £££. I just reversed the blade and pushed it back into the plastic slot and it works fine on cable sizes up to 25mm4c

I found this as well with mine, as the blade was running backwards and not scoring the steel wire that much. I turned the blade around in the holder like you said and now it seems to work better.
