Ohto Retractable Pen-Style Ceramic Cutter - Silver Body

Great concept, but not an ideal execution.

The clip is nice and tight, the silver body looks great, the knock mechanism is firm and fun to press and the pen is slim and portable. I loved the idea of how the blade is very small and sticks out from a faux marker tip; it seems a lot safer even when the tip is extended out. Replacement is easy as well.

However, the grip didn't seem to be very effective, since the grooves were shallow. The thing I have to complain about most, though, is the blade. It was sharp, but I couldn't see where I was cutting and the blade didn't cut through many sheets. Hey, it's not a heavy-duty knife, but the blade wore out too quickly. For something this expensive, I expected the blade to either a) get duller more slowly or b) have cheaper refills. But with 2 minuscule blades at 4 dollars, that's a bit pricey on my terms.

I still love the concept; it's quite a novel thing to have a blade disguised as a pen. Be careful if your friends draw on themselves! I'm probably going to get the refills anyway, since I actually love this thing despite its imperfections.

I found that the overall usefulness of this knife was limited by its blade size...when it cuts, the blade sinks in, and the plastic blade sheath is a view hog, so you basically have to guess really accurately as to where the blade will go next, or you have to rely on the much more conspicuous craft knife to get it done.
That said, the portability factor is down right awe inspiring, it is thinner and lighter than most pens. The clip inspires no confidence, as friction is all that holds it onto the barrel of the cutter. Yeah, so, take my advice, and purchase with your most practical part of your brain forward, or don't...you know what I mean, right?
