Heirloom gardening tools

TNye

I'm looking for a source (online) of professional gardening tools. I'm tired of spades that bend, pruning saws that can't be sharpened, and tools in general that are built to self-destruct. I'd also like to find a soil/compost "sifter" or sieve and will probably make one myself as they seem to have gone extinct. Where do the pros get their durable, repairable, long-lived tools that can be passed on for generations?

I'd go to car boot sales to find old tools. 
I have a fork, given to me in 1987 by a 72 year old gardener who told me he'd had it for 50 years. I use it all the time
