Absolutely fantastic for cutting rockwool on my recent shed insulaton project
This is essentially a long, serrated bread knife with a coarse and finer serration. The length and super comfortable handle make it perfect for cutting rockwool insulation. It's easy to handle and looks great.The included sheath is a nice touch though this wasn't particularly useful for me. In any case, the knife is nice and sharp and feels premium, appropriate for the price.I'll probably never need to use it again but it made insulating my shed a LOT easier.

Perfect for cutting around sprinkler heads
I had one of those circle cutters from the big box store and the handle twisted right off. Bought a second and the same thing happened, because they are built like toys. So, rather than flush another $40 I decided to try this knife. Aside from having to kneel to use it, this knife is perfect. Just cut a circle and pull out the grass and it's done. Works like a charm and it's built like a real tool. I don't see having to replace it...ever. Even if I did have to replace it, this was less than half the cost of the cheaply made circle cutter. Plus, I just like knives. LOL

Make Insulation Easy
Last two days we were renovating my garage getting rid of all the drywall and re doing the insulation, so the insulation for walls (21R) cost 90$ per 7 pieces and we spend around 1000$ just for insulation material for 1000 sqft garage. This blade make it easier to cut the fiber insulation and I can say that best 20$ ever spend. Cheap, effective, make my job easier and 1/5th of one bag insulation sheet and I am sure it will last a lifetime and make it easier for me many more times.So do not hesitate buy it, also like the blade cover really make it easier to store the blade.
