Review: DK06 Serrated Duct Knife from Klein Tools - Update: 10/17/2014_I've now had this knife for about a month or so. It sits ontop of my table saw, in the sheath, ready to grab in the garage, as I stated before, it's intended use. I have cut boxes up for the trash bin, to make thins fit more efficiently, cut paracord, stabbed a large roach, opened cat food boxes, scrapped the algae and barnacles from a trim actuator and in general used it more than I thought I would. This Klein knife is a dream. Big and sound. Sharp and holds an edge well. I like it more now than before, when I wrote this review. I've used Klein tools for years and after seeing this DK06 Serrated Duct Knife, I ordered it for a Garage Utility knife. By utility, I mean I will use it for almost everything I'll need to cut, box opening, poking holes in, and with the Serrated edge, most rope, cardboard box tear down, duct tape cutting and of course, the occasional zombie throat slitting and brain stab. It is a hefty knife and will work well for about any knife use you may have. I have a fishing addiction, which I don't indulge in near enough and this will work well off the bank, shore, pier or boat as a general purpose bait knife or gutting blade, where a smaller knife would be found lacking. It fits the palm very well when gripping the rubber handle and cleans up well with soapy water. The stainless steel edge was not very sharp, but useable when first pulled from the puncture resistant sheath for the first time, but a little time with the Smith Diamond Sharpener, the edge was smoothed off and the edge became almost too sharp for a utility blade and cuts like a new blade in a box cutter. The tang goes through the handle to a end pommel, that can serve as a flat faced hammer when handled carefully, so as not to stick yourself in the eye or something. The knife does not have a guard at the blade, but the handle there forms a flared guard like end to the grip. If you need a garage knife, a bait cutting knife or just a Duct knife, this will serve you well. I like mine for the price and love it for being a wicked dagger shaped Utility dual edged zombie weapon, that cost me only $12.92 with free delivery, with my Prime Membership, which is due for renewal at a higher price than last year. Of course.
Review: A good tool !! - Bought this a gift for my bf as he works with sheet metal a lot , he’s been loving it, says it cuts sheet metal like butter and helps a lot with making holes and overall use. Does say that it is really sharp and too be careful with it as it will stab you if your not careful. Would recommend this product for workers!!

### ⭐⭐⭐⭐⭐ Great bang for the buck!
*by S***S on October 4, 2025*

I have and use a number of knives. I work on a boat and carry a high quality knife with me every day. With that said, I noticed this Klein knife and was surprised at the low price. Thinking there may be some fluke in either the knife or the price... I figured I would give it a try. I ordered two of them. I figured for the price, they are almost disposable. Well, I received them and I am QUITE happy with the quality of the Klein knives. Have I seen better quality? Yep....but for $16? Nope...these are a GREAT bang for the buck deal.
