I have used a number of Stanley spokeshaves. When tuned up, and they ALL need it badly, they worked well. But when I got that Veritas spokeshave I realized what it was that I wanted those Stanley's to be.
I gotta tell you, Darksoul, there IS a difference. The blade I chose for my spokeshave is the A2 steel. I have worked over 18 months with this shokeshave and I have yet to sharpen it even once. I have stropped it on a leather strop with some polishing compound now and again, but it still takes hair off my knuckles when I want to! The bed to blade mate is flawless. I used machinest's spotting compound just to test it out when it arrived. Bang on, dead milled flat. The blade is more than thick enough that it cannot be warped by tightening down the adjustments.
The adjustment screws are finer threaded plus the threaded parts are seated into the tool body and have absolutely no play in them. Often my old Stanley would work loose and eventually I had to epoxy them back in their holes.
Running this spokeshave down a piece of wood is akin to driving a very well made Italian sportscar versus a run-of-the-mill economy car. They will both bring home the groceries from the store, but the performance and responsiveness is not even comparing apples and cobblestones, much less apples to oranges.
Here in the U.S. I can order Stanley #51's online and with delivery they would run about $38, for the Veritas it came to just over $100. But I didn't have to spend a couple hours trying to get the tool tuned up, sharpening a decent bevel on the blade, nor all the constant re-sharpenings, etc. It's a luxury tool in some ways, but I consider it a pretty cheap luxury when I amortize it over a lifetime of use.
