As my tests showed, this corner chisel is the perfect tool for precise cuts. It`s sturdy and well-made, so I have no doubt it will last me a long time.The sharp blade makes quick work of even the toughest materials. The only downside is that it can be a bit difficult to sharpen, but that's a small price to pay for such a high-quality product. Overall i highly recommend it to anyone in the Industrial and Scientific field who needs a reliable corner chisel..
