OLFA Precision Hobby Craft grafisk kunstknivsett (AK-4)

These are definitely a step up from your average hobby knife. As soon as you pick it up you will feel the weight difference. This has a very solid feel and at least twice the weight of an X-Acto knife. The grip of the blade is also far superior to the X-Acto system and it loosens easily. This is something every hobbyist needs and a cut *cough* above the competition.

The knife is well designed. The nub on the back keeps it from rolling off your desk and straight into your foot like an X-Acto. Seriously, why has no one addressed this before? The cap also fits securely and won't come off.

As far as blades go, it come with three, but you can also fit standard X-Acto blades in it and it holds them just as securely. That's good because X-Acto generally has good blades and they are cheap and available everywhere. I really purchased this as a saw. The OLFA saw blades are perfect for modelers and hobbyists who need a razor-fine cut.

This is the best hobby knife I have ever found and a pretty good bargain. Tamiya and others rebrand this knife as their own and charge 2x more. I will probably buy a few more to keep as spares.

Nice weight and Grip, standard #11 blades easy to replace but the most outstanding feature of this knife is the ability to keep blade secured into handle. used Xacto, excel... other brands and all of them seem to lose grip on blade and require frequent retightening

Once you get a good quality product like that it's hard to come back to the cheap knives. Cannot recommend enough, especially if you use those kind of tools a lot. It's worth the extra buck.
Functionality:
The grip is excellent. It won't roll off the desk.
Durability:
Very durable, has nice weight to it.

Glorious nippon steel

I use this for my plastic model hobby. (Gunpla)
