Review on Enhanced SMB Precision Heavy Chisel Blades: Optimal Tools for Accuracy and Strength by Mark Ponnusamy

Blades are as expected, good quality and very sharp. The only problem is that the base of the blade that fits the handle is too wide to fit the handle of any knife I own. Maybe it's my fault and I need to use a special pen. The listing says it's suitable for medium powered knives but I have no idea what that actually means and lists the blades to be made from Excto brand handles and they don't fit the three knives of those brand I own. I just used a dremel to carve a mark into a cheap knife handle to fit.
