I found a 2 stroke Powertorque with no blade holder, so I decided to sharpen the ones on this one before fitting it on, to see if it cuts better. Probably won't make a difference, but I wanted to try anyway since it was already off. I used a bench grinder and finished them off with a hand file. Bad idea?

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
