I have no idea what the best tools are but I know that I will never own them.
The best tool is a tool that functions. My off brand chinese concave cutters for 20 dollars have never let me down in 3 years time. Might replace them in 2 years because sharpening them is more expensive than replacing. So that's about 4 dollars a year. If I were to replace them with branded tools, they'd be old and rusted away before I'd reach the 4$/year break-even point. Not to forget the fact that I would have to get them sharpened every now and then for about 20USD because throwing away a 90 dollar tool because it's blunt isn't something I'd do. I think it's a never ending loop of sinking money into something I personally don't care about. I think I can live without those two tool-related compliments a year.
Found out recently that horse hoofsmiths tend to use similar tools to ours: scrapers, cutters, splitters, clippers, and so on. Same quality but a way lower price.
A wood scraper for 45 euros? How about a double sided hoof scraper, with ergonomic handle for 20?! Branch splitter? Hoof nippers are cheaper, same build quality and usually locally made.
Tools don't make the tree, it's the hands those tools are in. If you've ever seen a mechanic working with a screwdriver, you'd be amazed how little they use it to actually screw and unscrew things. I honestly can't even remember the last time I used a flathead screwdriver on a flathead screw
If you're in to smithing and collecting cool tools, be my guest! Those people deserve love too! I just don't get it.
