> My dad broke a Craftsman shovel once that he had owned for four years, took it to Sears, and it was replaced immediately, no questions asked. I broke a socket wrench that I had owned for a year and had the same story.

This is covered by consumer protection laws in some places. 4 years on a spade would be pushing it, but I’d try with a good one. Here in New Zealand it’s called ‘The Consumer Guarantees Act’. We pay more at purchase time, but we do get something for it.
