Review on Everhard Extra Long Insulation Knife with 5-inch Blade - Model MK46300 by Justin Santiago

I have used this knife to cut insulation and fiberglass tape underground and overall it works very well. I would suggest a few small improvements. I think it should come with a sheath for safety reasons to protect against an exposed blade when not in use. I improvised by wrapping tape around the cardboard sleeve. It would be nice if the pen was a different color than black. Sometimes it was difficult to see him in the darker underground. I improvised with red tape. I love the fact that this knife is non-serrated so I can sharpen it quickly and easily. I've found that the fiberglass insulation dulls the knife from what I've read online.
