could I ask for advice regarding bow saw blades?
As I do a fair bit of cutting branches and medium sized trunks I have invested in what I understand was a fairly top of the range (Bahco 24 inch) bow saw.I was fairly chuffed that it was displaying a replacement blade at just under 10 euro (new!!).
I have used this equipment for the past 10 days or so , on and off and was surprised when the job seemed to be getting harder (more sticking etc) over the past short while.I had not cut into anything other than wood (mostly green).
Returning to my old bow saw with its cheap oldish blade that I had nevertheless shapened as best I could (with a chainsaw file) and derusted with wet and dry enery paper I am a bit disappointed (well should I be pleased?) that it was noticeably better.
The expensive Bahco blade is ,I can see . the kind you are supposed to be unable to resharpen (it has the rainbow coloration at the tip and I think that means it has been heat hardened )
Do I draw the conclusion that these unsharpenable bow saw blades will not last for a very long time at their initial sharpness and that they can be outdone by a cheap blade that I am prepared to sharpen from time to time?
ps is it possible to over tension the blade?
Obviously not from the point of view of possibly breaking the blade or bending the frame.
But is it enough for it too be reasonably taut without obsessing over it?
