## Description

New Releases Concrete & Masonry Tile & Flooring Drywall & Paint Tools Cleaning Tools Step Stools

Review: 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.
Review: Very effective and good quality - My wife and I put down 4 pallets of sod using this knife to cut pieces as needed. The course blade was very efficient / effective for doing this.
