CUSTOMER REVIEWS

Rated 4.6 out of 5 by 15 reviewers.
Rated 5.0 out of 5.0 by Awesome for roofing Scoured internet for alternative to manual hook knife for cutting asphalt roofing shingles and barely came across this item. When I check Dremel website, it barely mentioned roof shingles so I was suspect it was really designed for this but tried. WOW! This cut 30 yr dimension asphalt roof shingles like butter! Had to do more than 250 cuts and the same blade cut as fast as I could setup shingles. Best solution for trimming installed shingles on roof. Very few local stores carry and very few people know about this on internet which is a shame. if this cuts asphalt shingles this good, I trust anything else would be cake. This is the best blade since the diamond sanding blade! October 30, 2014
Rated 5.0 out of 5.0 by Works Great! This Dremel multi-knife is a handy addition to the tool box. I don't have this brand of oscillating tool, but with the inexpensive adapter (MM300), this knife will fit other brands too. So far I have only used it to cut up stacks of cardboard boxes in the garage. It made the job so much easier than the struggle with the old utility knife, I'm impressed! I'm sure that cutting the carpeting we have to install is going to be a breeze! The blade is very sharp, and it comes with a handy soft plastic sheath to cover the blade when not in use. I like the double hook, giving you the option of using either a push or pull motion when using it. December 29, 2012
Rated 4.0 out of 5.0 by Cuts well but box cutter still faster for some uses The Multi-Knife is a good attachment to have on hand. It cuts very easily with either the hooked side of the blade or the straight. Does plunge cuts well. This item will certainly save time cutting material such as carpet or linoleum. If you are breaking down cardboard boxes that aren't oversized and only need to cut the tape, a box cutter is still much faster (no cords, fast swipe and down). If however you have a large box that needs additional cuts or is of thicker material, the Mult-Knife is the way to go. August 14, 2013
Rated 5.0 out of 5.0 by A great addition to my oscillating multi-tool! This is a very welcome addition to my Rigid Oscillating Multi-tool! The Dremel MM430 Multi-Knife accessory fits on my Rigid oscillating multi-tool tool with no need for adapters, but Dremel does makes a universal adapter to fit most any tool that the blade won’t fit. Like all Dremel multi-tool accessories, this blade can easily be removed by only loosening the tightening bolt – you don’t have to remove the mounting bolt all the way off like most non-Dremel multi-tool blades require! The longer knife blade makes great cuts by pulling, and it did exceptional job cutting an arc in my 1” foam insulation. No more cutting relief cuts from the flat side to the arc to get a smooth arc cut using a razor blade; no more rough edges using a carpet knife; using the pull blade on this cutter, I got a clear and relatively smooth arc in seconds! It makes cutting a relief to clear a pipe a cinch when installing insulation. The longer pulling blade even plunge-cut through a cardboard box, allowing me to cut a top off of a cardboard box. The blade cut straight and did not veer from the cut line like some razor knives have a tendency to. It was like I was cutting through warm butter. The smaller blade, used by pushing the blade through your material, performed flawlessly when I used it to cut an arc in some shingles. I use shingle material to top birdhouses and parcel boxes. (I can’t climb ladders any more.) This will make trimming the shingle material sooo easy! I can’t wait to use it to cut some leather when I need to. I just finished laying some tile in my bathroom and this tool would have been so useful then to cut the tiles when I laid them at 45 degrees to the door opening, especially around the toilet hole! One thing, though, this blade comes with a plastic sheath. DO NOT LOSE IT! The blades are incredibly sharp and the sheath helps protect the blades edges, as well as protecting your fingers in case you go searching through your cutters with bare fingers! Overall, this is a fantastic addition to my oscillating multi-tool! I am sure you will find many, many uses for it! January 31, 2013
Rated 5.0 out of 5.0 by AWESOME TOOL FOR ROOFING Searched high and low to alternative to hook knife blade for cutting thick asphalt roofing shingles. No one even mentioned this blade. Dremel's own website barely mentioned "...and roof shingles" so I assumed they didn't have confidence in ability to cut asphalt shingles. Picked up last one at home depot store and installed. It worked like magic. Had to cut 135 pieces of shingle to make ridge cap (which saved lots of $$$) which equates to 270 individual cuts. The blade cut 30 yr asphalt shingles like butter - esp when shingles were warm. Also the ONLY solution for trimming installed shingles while standing on ladder. If you have one or two cuts on roof, manual blade works fine, but with multiple cuts, this will safe you time, energy and unecessary cuts. BTW - it also cuts much straighter than manual blade.

Rated 5.0 out of 5.0 by Very handy for carpet I used this multiknife to cut old shaggy carpet in my son's room. It is much easier than useing a claw knife and zips through the strings, cutting an even line. This is very helpful when I want to remove carpet in small sections at a time. You can use the knife to cut in both directions, pulling it toward you or pushing it forward. There is a sharp point on one end, which is handy in starting a forward cut anywhere. Since the point is sharp, I usually attach the knife with the plastic cover it comes with until it is securly on the tool and then cover it again before taking it off. I would also make sure the power supply is not connected when removing it since not all multitools have this safety feature. January 28, 2013
Rated 5.0 out of 5.0 by Alternative to a utility knife I don't have a Dremel oscillating tool, but it fits great with an adapter. Mine cam with on so it can fit on just about anyone other there (check before buying, not sure on some of the newer tools that have tool free release mechanisms) I used this to cut up some cardboard boxes so they fit into the recycling bin. Worked really well on the thicker glued together sections. Made it easier then using a utility knife, plus there is a lesser chance of slipping and cutting myself. I am sure it would help in removing carpet. January 29, 2013
Rated 5.0 out of 5.0 by You can even do plunge cuts I had an unusual job for this knife. I needed to cut in a floor outlet in a carpeted floor. I have done this before with a razer knife, but it is not fun. With this knife, and the tool at medium speed, it was a snap. The push blade works well for starting a cut in the middle of the carpet, and the hook works well for completing the cut. You can use the push blade for the entire cut, but I like being able to lift the carpet as I cut. The hook end lets me do that. I stop the cut before finishing the cut, and change back to the push blade for the corner. I feel that it gives me better control. The push blade also does a nice job of cutting other types of installed flooring. I am looking forward to using it for trimming the next time I install flooring. It should work out great for trimming around cabinets! One thing to be careful about - the blades are SHARP. Make sure you wear a good pair of gloves when using it! January 9, 2013
