Hm.. When it comes to bonsai tools, quality and price most of the time go hand in hand. These look very similar. I think I would prefer the carbon steel, instead f the stainless. These can be sharpened better.
In the end the tools will both last a long time as long as you do not force them. The better the tool, the more abuse then can take before they bend. I basically only have cheap brandless tools, and find they work fine for me. But I do keep them sharp and rather do work in small steps, removing large sections small bites at a time.
