Love this knife for its holster and clip. I’m cutting boxes all day and no longer have keep looking for a blade as it’s attached to my hip. The 2 cons I have are 1) my belt clip broke after only a few months of use, but the price point was reflected. And 2) I also wish it came with more blade storage. Replacement blades are expensive and I go through a lot. I love the fact it’s made in the USAI bought this knife for my job as a stock person who cuts and opens hundreds of boxes a week. I love the added tape cutter feature at the opposite end of the knife so if you know your opening a box with a product that might also get cut when you open the box, this little tape cutter will break the tape without cutting into the product itself.Great color combo, easy access to the extra blades and the holster fits perfect on any pair of pants. Plus 3% gets donated to veterans so you can feel good about that.lo dejo en una puerta equivocadaThe box cutter is good but the belt clip holster that came with it is useless because is will not hold the box cutter.I dropped this at work my first night(had it on the leash) it landed with one of the safety sides extended and now it jams and I have to mess with it....Otherwise, this is way better than those yellow plastic ones!!Update-now that it has been a week. Now, the safety edge doesn't lock into place anymore. I have to use this like a 1,000 times a day. I'm trying to find a good quality one.I never used it and sent it back at $11.49. Try this one,Performance Tool W2610 Mini QC Utility Knife at $7.28, I bought 2 of these and there wonderful to work with and much smaller than the Spec Ops Tools Safety Knife Box Cutter. The 2 I bought fit on your keychain.Really like the holder and depth adjustment on this and the squeeze dagger is nice.I thought it was made of metal like most box cutters but it's made out of plastic. It still holds together well. Also it doesn't take standard blades. I seem to only be able to order them online/from Amazon. I have looked in stores and couldn't find them. Other than that it works well and gets the job done. Another thing about this cutter is you have to be careful when using the tape cutter on the back end of it because the button to pop out the razor is the length of the whole thing. So when you use it you kinda have to hold it by the button which can be dangerous because blade is now facing your hand/wrist. The only thing you can really do to avoid that is put it in the lock position by spinning the dial but that gets annoying trying to go back and forth from razor to tape cutter like I need to. Also the dial to change the blade length and lock the blade spins very easily while handling the cutter so you might think it's locked because that's where you last had it but when you grab the cutter out or the holster you automatically have to grab the button the blade maypop out and cut or stick you. Luckily I've only been poked like twice and not bad. I got away quick enough to avoid serious damage.Tive que comprar esse pack de lâminas, pois descobri que não existem similares no mercado nacional para o estilete com coldre SPEC OPS que já tinha comprado (e não existem mesmo, não é a lâminha trapezoidal comum, essa tem um tamanho diferente do normal) e decidi por esse produto, no qual vem 81 lâminas, o que vai me ajudar muito em não ter que me preocupar com substituições. O produto é muito bem feito, tem um reservatório para se guardar as lâminas usadas (para descarte posterior) e as lâminas são embaladas em papel (!!!) em grupos de 3, achei muito legal e como dito, o preço original eu achei caro, mas a qualidade do produto justifica. Recomendo.O estilete tem muita qualidade e cumpre bem sua função. Dá para ver que é usado materiais de qualidade em sua construção. O local de armazenamento das lâminas é perfeito. O coldre é ótimo para transportá-lo e o cordão deixa tudo seguro. Gostei e recomendo o produto.O estilete me surpreendeu pela qualidade da construção e da sua idéia em geral (regulagem do tamanho usado na lâmina com controle independente, o espaço interno para armazenamento de lâmina extra, o coldre e cordão de fixação, etc), gostei muito, conseguiram sofisticar uma ferramenta que parecia tão simples. Vale a compra e recomendo!Es más que nada para abrír cajas de cartón, la profundidad útil de la cuchilla es mínimaLamina retrátil muito curta e incompatível com outras laminas que eu já possuía.
