we have a big Fiscars lopper we got from my sister when she moved (so no warranty that I know of) but the blade broke when Mr. Dog was asking it to lop huge branches. But we found out they sell parts on their website, and new blades were only about $3 each. Easy to replace, and the loppers work good as new.
I think our local Menards sells Fiscars brand pruners. Good to know that you can get replacement parts. Whatever brand I buy to replace my Black+Decker pruners, I hope the company will stay in business long enough to back the warranty.
Update on my email to Black+Decker: I got an automated response from Black+Decker that they received my warranty request and that someone would be looking into the case. I don't know what they will do as they no longer make that model of pruner. Hope to hear from a real customer service rep this coming week.
