I'm gut-rehabbing a 4 bedroom colonial. There is no shortage of places to put my time. This speeds up the process of cutting and fitting batts and getting a neat, clean job done. Add a hammer stapler and a tape rule, and fly through your project.

Excellent after a little tweaking

As the knife comes from the factory it is extremely difficult to use. It is not sharp enough to cut foam thicker than 1", and it is extremely hard to push the blade through thicker foam without crushing, rather than cutting the foam. I purchased a good ceramic rod knife sharpener and sharpened the blade. This was much better but it was still very difficult to cut thick foam because of the friction of the huge blade sliding against the foam being cut. I sprayed the entire surface of the blade with silicone lubricant and this made an almost magical difference. It was trivial to make very smooth cuts in foam 3" to 4" thick.

For some reason the Amazon web page is not letting me set my star rating but I would give it a 5 (if Amazon would let me).

WOW!!!

Having worked three summers in High School as an insulation installer, and insulating several homes since, I can say I haven't ever used a knife/saw that cut insulation this well. I recently bought the saw after reading about it in a tool review. I finally got to use it on a home project and was amazed how cleanly it cut. I would recommend it highly.

Why didn't I find this 30 years (and 4 houses ago?)

The first cut I made with this knife in a fiberglass bat I almost wanted to build another house so I could use it more.(I am 99% done with the present and last one).I install my own insulation ,even though I hire out everything else, because it is the only way to get a nice job ,with tight fitting seams.The clever curved blade design causes the insulation to be sheared like a scissors does.Since the whole length of blade cuts ,rather than a very short length using a conventional knife, the blade stays sharp longer.

Good Tool but needs to be sharpened better

This is a well made tool overall. Although it does not tell you in the description - it does come with a sort of sheath/edge guard.

I was disappointed that the edge was not sharpened very well when I received the tool. It had a very heavy burr on it that had to be sharpened off to make the tool usable.

If you plan on buying this tool make sure you can sharpen it before taking it on a job site.

USELESS TOOL-Save Your Money!!!

If you are considering this tool for use on Ultra Touch insulation dont bother. The tool is absolutely useless for that application, maybe it works well on other "conventional" isulations but it does not work at all on the ultra touch material, you are better off using the standard utility knife (carefully) and straight edge. If you are using Ultra Touch insulaion the best way to cut it is with a small Band Saw (maybe even an electric carving knife), anything else is just a compromise. I write this as I am finishing the insulation on a 20'x20' room, BTW the Ultra touch insulation is Excellent, very happy with it.

CEPCO Tool IK-10 Insul-Knife is Junk

2008-04-20
I was Very dissatisfied with the CEPCO Tool IK-10 Insul-Knife I purchased. I returned it for a refund immediately. It was very poor quality. The blade was bowed (curved) so no way could you cut straight. The blade looked like it was made from a cheap flimsy piece of sheet metal. The blade was also very dull - I'm sure it wouldn't cut through butter let alone insulation. - I ended up buying a heavy duty box cutter with the 4" blade that is segmented so you just break off the blade tip as it gets dull. I extended the blade all the way and this gave me a nice sharp almost 4" blade for cutting through insulation.

After years of cutting insulation with a utility knife I have to say this product is wonderful. This knife is a great time saver. Try it and you will see.

HOWEVER---I was not satisfied with how sharp the blade was.

I sent it to a sharpening shop to put a proper edge on it.

That's all.

This is a must tool for anyone doing insulation. Makes a perfect cut without all the jagged edges. Highly recommend this tool.

I would have rated it 5 stars but it had small areas of rust when I received it.
