XH Automatic-Lock 18mm Wide Blade Cutter

Pros: Nice and Sharp, retracting mechanism is easy to use, handle is easy to grip. Does everything that you would expect it to. I have used it to cut thin and thick plastics, paper, cardboard.

I wrecked one part of the blade on some thin metal but I got through it which is a recommendation in itself - I snapped off the broken part and it was good to go!

Cons: None - works perfectly.

Other: If a retractable knife in this style is what you need just buy it!

Pros: - Very sharp blade
- Nice step level locking mechanism

Cons: - The packaging box it came in had blades that were colored yellow and red but inside was blue, not really a con but its just something to fill up this space. choice of colors maybe?

Other: nice to use, very sturdy, cant see it breaking apart soon. It looks larger in real life than it it appears in the photos.

Pros: Good price
Nice firm handle
Locking mechanism simple and clever
Pretty blue

Cons: Blade holder rattles about (this is disconcerting but not functionally important)
A few free blades would sweeten the deal as blades blunten quickly
Can't be stored in plane carry on luggage

Other: Good, reasonably priced cutter, for boxes, and other uses. Recommended.

Pros: - It simply works.
- The companion blade is very sharp
- It came with an extra blade!
- It has a place to hold one (maybe two!) extra blades inside
- It has nice handling, steady and firm.
- Looks resistant.
- The autolock works just fine;

Cons: None I can think off.
It could be prettier and have better colours, but honestly, who cares? :-P

Other: You should buy it. 18mm is a standard size, so you'll find replacement blades at any regular store.
