Klein Tools DK06 Serrated Stainless Steel Duct Knife with Sheath - Professional HVAC Cutting Tool for Flexible Duct & Duct Board | Perfect for HVAC Installations, Construction & DIY Projects

Great designUpdate: 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.Best especially for price. The sheath is trash but if you don’t wear on hip , you may not mind. Stays sharp, easy to sharpen. Nice blunt hammer end. Really toughFeels great in my hand, looks great, and cuts through any insulation like butter. The plate on the bottom of the knife comes in handy as well. Super satisfied.Super strong and durable. Been using this knife for over 8 Months and it is still fantasic!Bought this a while ago and it's still holding up strongThis is a quality tool! The handle is high-friction rubberlike material, comfortable to hold, with nice safety points for one's thumb to rest and push against. There is a real, actual, steel cap (not shiny plastic) at the end of the handle that is embedded a half-inch or so into the back of the handle. Within reason, it could be used as a hammer. The blade is about 1/2 tang, maybe a little more, but the handle is so solid and sturdy that it's hard to imagine that one could ever break the tang. The blade itself is a robust 3mm in thickness, 5 1/2 inches long. The serrated side of the blade has a feature that I have never seen before--there is a small grind on the back side of the serrations. By carefully honing that grind with a round diamond rod (Smith's make one), I was able to produce even sharper serrated edges. The nylon sheath is probably better than most and would be fine for a tradesman using this tool in HVAC work, but I don't like 'em and made a nice leather one. But that's just me. Also, the straight edge was not very sharp as received, but by pulling it through my Rada sharpener a number of times a nice sharp edge was achieved. This knife will not disappoint, however it might be used--building trades, camping, even for self-defense.Had a knife similar to this one - different brand. Lost or misplaced it somewhere, so I needed a replacement. This one seemed to have good reviews and was a decent price - so I ordered one. The knife seems well made. The blade is sharp enough for what it does - cut duct work & foam board. I like the style of sheath that it came with - better than the hard plastic one my previous knife had. I'm happy with my purchase.This rather expensive knife seemed OK for cutting things however it has a brittle blade made of very grainy metal, and when I tried to dig a weed out of the garden with it, the blade just snapped in half! The blade is not as posh as it looks... The description says it is for cutting, so stick to that and you'll be OK.If it’s still up for £16 it’s a steal.Feels full tang judging by sturdiness and how the weight is balanced towards the top of the handle.Fits well in hand. Not crazy sharp but good qualityEdit: after about a year of use I’ve found it to be a pretty good knife for multiple uses after sharpening and the serrated edge makes it by far the best bread knife I’ve ever come across.I do a lot of beach cleans and recently come across a large amount of ghost fishing net tangled up under some cliffs, it needed to be cut up into smaller sections which could be then dragged out. This knife with its serration down the full length of the blade was exactly what i needed to get the job done. It cut thought 3 inch rope, plastic and natural fibre netting as well.Knife is blunt and struggles to slice through things which even a butter knife can. Very pricey too.Larger than expected and amazing quality very impressed with this knife
