Bought to cut straight line for aco drain which it did well. It kicked at little if I went too deep but otherwise was a quick smooth cut. Blade should have the longevity to cut all the French drawing I will create around the house. The disc need tightening as it warmed and had to loosen after use else would have jammed. £120 for blades and saw very good value. Photo of saw cut attached first time using a tool like this.
