The thought of getting a slick for myself actually arose from the fact that I found myself supporting my chisels against my waist or shoulder while paring some of the joints. Now especially when working with the chisel in a vertical position, I find it difficult to get my posture just right, which made me think I could benefit from using a longer tool instead.

Rounding the back never crossed my mind, but I can see how this helps in the paring process. I will probably try that out with my regular paring chisel, it really seems like a very good idea, especially in terms of getting a smoother finish with less effort. And if I figure this out correctly, having the back ever so slightly curved, also results in the cutting edge coming out with a slight radius when the bevel is ground flat.

But I won't be giving up the idea of obtaining a slick just yet. I'm in no hurry, though. So I have plenty of time to ponder any options that might come by.
