We received one of these Pencil Knives free of charge from Jet Pens a few weeks ago at HQ for reviewing. I have used this little knife for a while and have probably taken it to inappropriate places in my pocket over these weeks. So believe me when I tell you that this is a cool little knife, one that has been tested.
First, it is a safety knife, but it is still a knife. Don’t give one to a toddler or someone with tiny fingers. That said, it is difficult to cut yourself with it if you are careful and use it for what it is meant for — sharpening pencils. I am a man who brings accidents down upon himself, and I haven’t cut myself with it yet.* This is a very pocket-friendly knife. It takes up about as much Volume Real Estate as a pocketknife, but it is very light. I literally forgot it was in my cargo shorts pocket on several occasions, almost leading to a Washing Machine Test. The blade assembly slides out and locks into place with a satisfying click, and there is a thumb indentation for ease of use.
I want to stress that using this knife is very unlike using a regular pocketknife to sharpen a pencil. The blade is thinner and is curved. Because of the safety guard, you cannot chop off large hunks of wood or graphite from your pencil. This knife works in a sort of semi-shaving action, taking off small pieces of the pencil with each cut. This means that it takes some time to bring an unsharpened pencil to Readiness for Action. But it also means that there is a lot of room for error. Because it is so unlike a pocketknife and because it takes off so little of the pencil at a time, this is an ideal sharpener for someone who is interested in taking up knife sharpening but perhaps is nervous about losing a digit or is intimidated by slight difficulty of sharpening a pencil with a knife.
After several weeks of use, my review unit is still working very well, without significant dullness or any rust. Certainly, replacement blades would be a boon to this system, but the $6 price tag is not so steep. I really like this knife for touching-up points while I am out, when the pencil just needs a little nudge back to sharpness. It is lighter than some brass pocket sharpeners, but the volume keeps it from falling out of my pocket.
Plus, did I mention that this knife is just cool?
* Knock on wood.
