Usually that folding feature locks into place, so for just what you want it to do, it will be perfect and last you many years. Now, if you were sawing with it every day and exerting a lot of pressure on bigger stuff, it may be a weak point...don't know?Same tooth count? That sounds like a good option. I only have 2 apple trees to prune. Of course, as the orchard grows, my pruning chores will be greater. It's my goal to keep those standard trees at a height that I can easily work them.
I didn't want a folding saw, b/c I consider the folding joint to be the weak spot of the saw. But, it sure would be nice to be able to tuck it in my pocket.
