Orr heat up a knife then place it on the hole slide it over gentlyā¦.
As an afterthought if your using your saw again and manage to lop off a arm or leg you could use the above technique to cauterise the cut enabling you to carry on with your trip, I got the idea from watching a old flim which I believe stared Tony Curtis called, now I could be wrong here but im going to say The vikings he unfortunately had his hand arm chopped off and a quick fix in them days was to set fire to the cut to stem the blood
I can thoroughly recommend the film š
Best of luck with saw and trip.
