ALLEX Insulation Knife Wood Handle 8" Long Cut, Japanese Stainless Steel, Insulation & Styrofoam Cutter with Sheath, Serrated Sharp Duct Knife Tool, Made in JAPAN

This knife is awesome! Have done entire interior and still sharp. Great knife!

Purchased two knives this one and the Grip Right with the red handle. Used the Grip Right after being 3/4 through the project and noted that the handle is inferior, the blade is too short, and the blade appeared to be dull. In short, this knife was head and shoulders superior to the Grip Right knife. I highly recommend this knife. Finally, I was a State Certified Residential Contractor for 30 plus years and know a quality tool when I see one!

Used to cut foam insulation panels to insulate garage doors. Out of the package it was dull af. After sharpened it was miles better. It's certainly not special in the material of the blade/handle. If inflation made it go up another $3 it wouldn't be worth it but as purchased it did fine.

Great knife for cutting polyurethane foam for a gun case. Previously tried using a hobby knife and thought I'd give this a try - Japanese are well known for the quality and genius of their hand tools. Works perfectly with the fine serrations using a controlled sawing motion. Some challenges with navigating tight turns but definitely better than the hobby knife. Won't buy again because it works so well and I don't need another...

Used it for cutting insulation styrofoam for the garage door. Made it so much easier. Totally worth it

This is a great knife, have used it for several purposes, including cutting insulation. It's a great size, it's sharp and seems durable.

This knife works very well for cutting insulation.

Not only good for cutting bats but also great for cutting a roast at christmas.

I had previously tried several other knives & saws for cutting insulation with little success. This knife was a game changer and went through mineral wool insulation like a hot knife through butter. It's actually turned insulating the loft into a relatively easy job.

柄の部分が少しカタカタしますが、それなりに良く切れます、ALK2425の1本も、真っ直ぐ輪切りに出来ます、3週間使いましたが切れ味も今の所、変わりません

よく切れます

特になし

最初、地面に対して並行に刃を入れていたのですがあまり切れなかったので吸音材を台のうてに置いて垂直に刃を入れるとスルスルと切ることができ感動しました！手を切らないように軍手は必須です。
