I think the reason they don't guarantee the blade is he fact that it is replaceable already. Being it is steel and the handle is plastic I would be more concerned about the handle. I have never used a pruning saw that small, I guess I felt that I could get more use out of a larger saw for larger branches and still use it on the smaller ones also. I did not plan on carrying the thing in my pocket so I felt no need to get a folding one. I am not saying or implying that this would not be a fantastic saw for some one with a need for a small folding pruning saw.
I have not been disappointed with any recent pruning saw I have purchased, they work so much better than the old ones I have had, the blades seem to be much better designed and hold an edge much better and are so sharp, I have just about stopped having a need for my chain saw.
