Amtech S0150 2pc Snap-Off Blade Disposable Retractable Knife Set, Craft Knives

Always good. Sharp.

I bought one like this at a low cost supermarket and found it excellent value for money. These Amtech ones are very similar and are slightly more comfortable to hold. New packs of blades are fairly inexpensive, so a very sharp cutting edge can be maintained at all times. The handle allows for a large concentrated cutting force. The blade can be extended when a wide- or long thin cutting edge is required, and retracted afterwards. Spare blades can be carried in the handle, by pulling off the end cap and inserting them in the chamber revealed. You may want reduced side play at the metal end of the blade holder. This can be reduced by gently squeezing it in a vice. Blade wobble is eliminated, making accurate marking-out possible. I use this knife in preference to all others, including the good old Stanley knife.

Very sharp, great large blade, great for cutting lawn turf into shapes you need it. Only used for this purpose.

Good for short term use and nothing thick either. replacement blades can be bought but apart from that, the quality of the plastic casings are not as good as hoped.

Very happy with my purchase

Not sharp enough. Difficult to snap off blade. I need something scalpel sharp and easy to refresh by snapping off a blade.

Great stuff

Used these all few time now and they do the job
