Just got this but already put it to use and it's proving a very good tool. It's a no frills handle but the blades are very sharp and rotate well when cutting curves. I'd recommend picking up spare blades when you purchase. They're not expensive and are cheaper still when purchased together with the handle. Plus you'll have them when you need them. If used with only sufficient light pressure as required I suspect the blade will last relatively well although I've not yet confirmed this. It definitely gives a clean smooth edge to smaller sharper curves so I'm happy to recommend this as being a useful tool and worth the investment. Great value!
