The best utility knife blades.

Incredibly sharp.
Amazingly sharp. Considerably sharper than standard Olfa blades. These don't cut so much as glide through. Well worth the money.

Cuts so beautifully it'll make you cry.
I love this. Every time I tear into a new piece of foam core it fills me with joy. The black edition definitely cuts for longer. It stays sharp for more cuts, and is just amazing to look at. If you are one of the few people who get pleasure from getting clean cuts, you'll want to have this in your life. Now. I barely use any other blades/cutters. No flimsy exacto knife #2 for me. No 10000 little blades to buy. This blade and the olfa holders gives unexpectedly clean/easy cuts that are VERY precise. Once you master this in your hands, you'll save a lot more time just cutting with this, instead of switching out blades all the time. I am an art student and dependable/sharp blades for clean cuts is VERY important to me. I wish I knew of this blade/knife combo when I first started my art education, instead of in the middle of it. A++++++ all the way. Get it. Feel the power. If I could, I would cuddle next to my blades. But the student loans are stabby enough.

Never going back
I use utility knives like...I dunno every day. I wear pants and have a pocket specifically for knives because I need knives at work. I bring a utility knife with me everywhere. I gave up on the utility knives because of expensive blades and constant changing of blades. These blades last a very long time and to change them I just snap off the dull piece. Im never going back to Stanley knives and blades.

No son tan filosas como esperaba, las compré para cortar aislamiento térmico, esperando que lo cortaran como mantequilla pero en realidad se atora durante el corte y queda mordido el acabado, supongo que para papelería están bien.

These are probably some of the best blades I have ever seen in action. They cut effortlessly in soft to mild materials and have easily breakable blades. I'd definitely recommend getting a nice Olfa knife that's compact and allows an easy grip. Just watch as the knife does the work and take it easy as to not cut yourself! :)

Hatte das set schon seit über einen Monat und habe nur ne Klinge verbraucht. Wegen der Serien Streuung weiss ich jetzt nicht ob der Rest genau so gut ist wie die eine aber es hängt auch von der Arbeit was man macht . (Zement Säcke eher mit Carbide aufmachen/ Folien, Karton geht locker) .

These blades are very sharp at the moment they are being used as paint removal tools. But they are excellent for trimming wallpaper They also make an excellent blade for scoring pork jonts to get the best crackling you ever had. Be careful they are so sharp that you won't notice when you manage to cut yourself!
