Bit pricey so off-putting for some but for me .. buy once and keep forever. Funny thing is, bought it to cut some 10mm copper for a one off job and then couldn't find my regular 15mm pipe slice so ended up using it on various. Actually quite like the shape as was easier to turn than my circular cutter. Worth the investment. I plumb fairly frequently and often find it isn't till you buy something you wonder why you didn't do it sooner. In my case small bore pipe. Love it !
