The Dual Duct knife is made in Taiwan. **Q: i lost a screw that holds the belt clip on a box cutter knife. it is a star type head. I can't find a replacement. where can I find one?** A: Try a hardware store. **Q: What is the distance between the mounting holes?** A: not sure what you mean about mounting holes, but be aware that the 71010 is not a true full tang knife like the wood handle version .. I have both and the 71010 will give a much better grip but I wouldn't chop with it .. **Q: Does it cut good on iso?** A: Some people like it for ISO board. The blade is kind of thick so the thicker the ISO board, the harder it might be to cut through. Most contractors use our MK46000 for ISO.

Realizing the potential of having a dagger type knife with both a serrated and straight edge, I decided to try this model (with the rubberized handle). The wooden handled model has proven to be very difficult to sharpen (meaning the straight edge, the serrated edge is quite keen). This high friction grip model was very easy to sharpen (using my favorite sharpener of all time--the Rada. A Rada sharpener will work wonders on any sort of blade I used it for, from heavy duty survival knives to the delicate scandigrind Moras), and the serrated side is quite sharp to begin with. There is a subtle difference in the two models: The wood one is 3 mm in thickness, whereas the rubber one is 2.5 mm. The rubber model also seems to be a bit more nicely finished, but is not full tang--about 1/2 tang I would estimate. Its pouch (sheath) is decent and probably sturdy enough. If any reader is interested in what these knives have to offer (that long serrated edge is very impressive!) I would recommend the rubber handled model--DA71010d--based on my experience with both. ### ⭐⭐⭐⭐⭐ Nice TOOL !! *by A***. on February 7, 2015* Bad to the bone ! Sweet dagger for trade work. I jam it into just about anything to cut and pry and this is a budget blade so I don't feel like I am about to wreck a overly priced tool. This is what you need to be a trade worker and have to get something to unlatch or pop apart and or cut or even just to get into a plenum and fetch. The sky is the limit. The price is amazing. The look is amazing. It fit in my hand and feelsLike I could depend on it for my life ifSome danger were to arise and catch meDefenseless I definitely could use this to hold my own and get to safety to call the authorities. My employer outlaws it on my person but it's got tool printed on it soCan sneak it past security in my tool box as a legit tool. But one day they willBe on to me and make another rule to make guys like me have to justify my hammers, saws, razors, putty knifes, and punches. It's eventually going to be so difficult to get work done that this will be outlawed everywhere. But it's a low budget tool that works well. ## Frequently Bought Together - DA71010 KLENK TOOLS Ergonomic Dual Duct / Insulation Knife - Knoweasy Zip Tie Tool and Tensioning and Cutting Tool for Plastic or Nylon Cable Tie - Ridgid - CC247 RIDGID 40617 Model 101 Close Quarters Tubing Cutter, 1/4-inch to 1-1/8-inch Tube Cutter Silver --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/12825990-da71010-klenk-tools-ergonomic-dual-duct-insulation-knife](https://www.desertcart.is/products/12825990-da71010-klenk-tools-ergonomic-dual-duct-insulation-knife) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-04-22*
