About a month ago I was down in my shop just cutting away and my blade broke.No big deal.Just put in another one,But as I pulled it out I just happened to noticed where it broke,close to the bottom of the blade.So I tried something.I put the blade back in adjusted the top clamp,and started cutting,and to my surprise I had a New blade!!.I t lasted several more hours.I now do this with all my blades,when they start cutting slow or burning,I take them out snip off about 1/8,and continue cutting.This may be old news to some.I just thought I would pass it along.Maybe it will help some Beginners.
