TAJIMA Utility Knife - 1 7-Point Rock Hard Snap Blade Box Cutter with Dial Lock & Rock Hard Blade - LC-650

good tool for doing insulation

Great blade. Actually the best blade I have every owned with regard to tough, out side work in construction or farm use.

The best utility knife, what else can i say. They should have made them this way from the beginning.

Great for the price and quality

Versatile cutting instrument with length adjustment. Very handy, I have and use a few of them.

Performs as advertised.

The insulated pipe that I work with has a black plastic shell. Other utility knives wont lock the blade well and when I cut the blade pulls out of the knife. This cutter gets the job done!

I do a lot of wood carving, these knives are the most durable out of any razor knife Ive ever used. I use them to aggressively take off large amounts of wood when I need, so they end up seeing quite a bit of abuse. Highly recommend these, and the blades they come with.

If you want to carry one box cutter in your workshop apron, this is it. This cutter holds a thicker and wider blade than the usual box cutter, and I have two of them - one for the work apron and one for the tool drawer. I also have a rubberized Stanley version but much prefer the solid hard feel of the Tajima and the minimalist look. Unlocks and slides out easily, cuts through thick cardboard easily, as well as thick nylon strings, thin packing film, packing tape, thin rubber or leather sheets etc. Well constructed and solid, no wobbles.

this is a great knife if you need a new sharp edge often and dont want to change blades, or need to cut thick stuff like 4 ridged insulation
