content: Expensive, yes. But if you make your living with tools, this one pays for itself in no time. This is one of those tools that most people wonder what the heck will I do with this $400.00 plus tool set. Once you have it, you'll be using it all the time. Yes the e cut blades are outrageously expensive, I've bee making my own by cutting miter box saw blades and push/pull blades and welding them to a 1/16" piece of metal that I bend & drill to match the mounting shoulder on the tool.Each blade takes about 10 minutes to make & I can make about 15 blades for under $20.00. The flush cut blade works better than the Bosch Fine cut, but the Bosch cuts deeper. The grout removal blade works like a charm and is way better & faster than recp saw grout blades. All in all if you are a renovation conttractor that does many different tasks, this is a great investment and you won't be sorry you spent the money.
