Rated 4.8 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by Reliable Titanium non-stick stiff taping knife works great. I used it to finish up my garage and it applied coverage evenly. The job I did was finished in no time. You can use this on the toughest jobs without adhesive buildup. When I was done with my project, clean up was very easy. Made of very durable materials. It will not rust. It has a hammer end to help set drywall nails while you are working. The non slip grip makes it easy to control, and comfortable to work with. The knife is made of high quality materials. I would recommend this taping knife. December 20, 2013
Rated 5.0 out of 5.0 by Easy to clean and won't rust? Yes please. This isn't my first ACME Titanium Nonstick knife, so when I have a chance to get an 8 inch taping knife I jumped on it. I like the flex in this knife and it makes joint compound application easy. Best yet, it cleans up so easy and no rust like my old non-coated knives. January 5, 2014
Rated 5.0 out of 5.0 by I prefer the stiff blade Over many years of doing residential and commercial renovations I've progressed from plastic knives to carbon steel to stainless steel. On a whim I decided to try this titanium coated knife thinking as long as it's as good as stainless steel I can't lose. It's much better! Even when left uncleaned nothing sticks to it and it won't rust. The cushioned non-slip grip is very comfortable to work with and the softened edges allow for perfect corners. In larger knives, 8', 10' and 12' I prefer a stiff blade which makes it easier for me to feather out imperfections in the wall. January 4, 2014
Rated 5.0 out of 5.0 by It gets the job done! This ACME 8 in. taping knife is a nice addition to my 4 and 12 in. taping knives. It's a nice in between for jobs not small but not large either. It allows much better floating and feathering of compound around drywall seams. This blade is nicer than my other two as it is non-stick, has a nice comfortable handle with a strike plate on end, and so far doesn't appear to rust if any moisture is left on it. My other blades are steel and I always have to ensure they are completely dry before storing. Also this knife by ACME seems to have a little more flex in the blade making taping and floating a little more enjoyable. If that's possible? Not a job for everyone but if you must then I would highly recommend this ACME knife. January 11, 2014
Rated 5.0 out of 5.0 by A keeper I like the flexibility and more than anything - the clean up. I specifically left some joint compound on the knife overnight, and almost all of it came off easily without a sponge and water. Hopefully it will resist rusting in the long haul. It's no doubt the nicest knife I've just for applying - especially the tape. October 30, 2013
Rated 4.0 out of 5.0 by Nice Taping Knife for Drywall and Plastering This is the second Clauss Acme tape knife I have, the other one is the larger 12” size. You need several different sizes on the job and this is around the middle size. I got a second one because I found the first one to be good quality. Not much difference between the two sizes except this is better for butt taping drywall in tighter spaces. I use the largest size I can get away with for finishing if it's more than just patching a nail or a ding. I like the handle on this knife which is plastic and feels secure with the lighter weight blade . Also, the titanium coating does a nice job cleaning up after dried joint compound which doesn't stick. Rust is not an issue and the manufacturer says the coating is stronger than stainless. The problem with some of the bluing blades is they rust with time and stainless is a heavier knife which you do notice . This one is lightweight and good at cleanup. In any case, its already gotten good use in a short time. September 4, 2013
Rated 5.0 out of 5.0 by Works great! A nice stiff blade with just enough flex for a smooth coat. My second favorite part is the handle, it is very comfortable which makes using this for hours less of a chore. The non-stick blade makes cleanup a snap. January 6, 2014
Rated 5.0 out of 5.0 by Love the non stick, no rust surface I used this knife the day it arrived. I am in the middle of some spackling work and my current 8 inch knife did the job, but needed to be cleaned of rust after it dries of from cleaning. This version has a Teflon surface which does make cleanup easier, however, I never found cleaning my spackling tools that hard, so take that for what it is worth. Where this knife stands out is that the coating prevents it from rusting and the blade has just enough give for finish work. It is also a few ounces lighter than the typical blue steel knife most of us use, which doesn’t seem like a big deal but if you are working for hours, the reduced weight is always welcome. I know that some tapers leave their tools in the bucket of water during the work day, I am a diyer and don’t do that, but if you do the Teflon coating will help keep the tool from rusting for sure. The handle is composite so no issues with water. Regardless of your level of expertise, if you are looking for a new taping knife, you have to consider this for your tool box. September 4, 2013
