PVC pipes of the couvid type, Kassinakis with a diameter of 16mm and 20mm, are difficult to cut with slow use always speaking. As for the PVC courbi pipes of 16mm, unfortunately, they get scratched no matter how slowly you cut them. I imagine they are exclusively for cutting very soft tricoclair pipes.

For 10 euros, the tool is excellent. [If you want a more expensive and better blade, buy a fully hardened SK5 steel (coated with PTFE) and not a Chinese alloy like 3Cr..., 8Cr..., 9Cr..., which, although more stainless, is much less hard and the edge easily wears out. Also, if you want to cut a larger diameter, e.g. 63mm, buy the HARDEN 600854 or the YATO YT-22273.]

It is very good, it is made of aluminum and cuts plastic pipes perfectly!!! It is user-friendly and convenient!!! I have had it for about six months and I am very satisfied with it. I highly recommend it.

Guys, I bought this particular one four years ago, and I have cut countless PPR pipes and fittings with it and it still hasn't had any issues.

I do not use it for fully professional use, but I use it quite often. I have had it for over 5 years and I only apply WD-40 to it periodically and it cuts perfectly
