Use this style knife several hours a day, construction related job. The knife body holds up very well, but the "wedge" shape has a different fit in hand. Still, very good price, quality product. ### ⭐⭐⭐ Cheap wrapping present DANGER *by A***E on May 16, 2014* Opened the carton (like book cardboard) pulled first out and reached in to pull second card out. Pulled hand out quickly as the entire blue container of extra blades was loose in the the box. The knives were attached to the cardboard and are very nice. But the blades were loose and just wrapped in cellophane with the knife package. Because of the weight of the blade package it broke through the dry feeling, crinckly wrap. The top of the blue blade container then opened spilling into the cardboard box. I would have given it a 5 star rating except for the extreme DANGER presented to me. AMAZON YOU NEED TO AT LEAST PUT THESE PACKAGES IN A PLASTIC BAG TO REDUCE THE DANGER TO THE CONSUMER. Would prefer you do something about the package wrapping. Thank you. ### ⭐⭐⭐⭐⭐ Great Value! *by C***C on July 11, 2014* A fantastic utility knife that I been using regularly for months to cut cardboard and spines off books for scanning. This cuts deeply and precisely - and yes the blades are sharp! Being a lefty, I love that I can hold this with my left hand and still get right up to the edge for a perfectly lined up cut. Given that this comes with snap off blades, plus 10 replacement snap off blades, this item is a tremendous value and will last you quite a while. ## Frequently Bought Together - SDI-5431 Snap-off Utility Knife with 12 Set of Sk2+cr Blades, 18mm Heavy Duty Rubber Grip Cutter for Right or Left Handed User, Pack of 10 - HEIKIO 18mm Snap-off Blades, 50-Pack, Quality Black Carbon Steel Made, Sharp and Durable, Heavy-duty Replacement Blade for 18mm Box Cutter and Utility Knife --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/17056656-sdi-5431-snap-off-utility-knife-with-12-set-sk2](https://www.desertcart.com.ar/products/17056656-sdi-5431-snap-off-utility-knife-with-12-set-sk2) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-12*
