Some time back I had to decarpet a large house. I set about the task with my trusty dodo which litteraly ate the job for breakfast. I found I could cut about five feet per swipe by stretching my arm out as far as I couls in front and cutting straight back as far as I could. The reverse s blade is small but it sank right in and never slipped out once. Job done and it was still razor sharp.
Conversly, last week I had to do a little bit of carpet cutting in an alotment. I used a stanly as the carpet was obviously clogged with soil and I didn't want to knacker the dodo. It took forever. I could only cut a foot or so each swipe before the blade jumped out and it was blunt and needed replacing after about 5 feet. Thankfully I had a fair few spare blades but it was a real pain.
Anyone in the carpet game or got any experience/tips they wish to share?
