I use the stanley knife for sharpening my colouring pencils. Easy to manoeuvre and comfy in my hand. Mainly used for decorating purposes such as cutting wallpaper and vinyl.

Lightweight, easy to use, very easy to change the blade. I like it's retractable and not on spring so blade stay out untill i decide to put it in.

The knife is cheaply made - but for the amount of work it gets put through it’s brilliant. But for a few quid it's not bad. Noisemaker is a good value for the money.

This is ok, but fiddly to put together. Blade is thin and whole contraption is flimsy. Only redeeming feature is its retractable and even that is beaten by the spyderco ladybug.

I'm actually surprised it's still on the market – indeed, i'm amazed it's even legal. This is absolutely useless.
