I wasn't sure what to expect when ordering this but I'm glad I did. Small but very easy to use sharpening your utensils.

This is an interesting little product, and overall I would say it has mostly helped me, so worth the small price.When learning to sharpen a kitchen knife, getting the angle right is one of the hardest bits it seems, and so vital to success.This helps you do that, albeit slowly and with a fair bit of hassle.It magnetically sticks to the knife, and helps you line up a consistent angle. So that bit is great.The problem comes when swapping to the other side of the knife, you have to keep taking this thing off and repositioning it, probably 30 times in an average sharpen.In a way it’s a design flaw I suppose, but I can’t imagine how they would change it.For me I’ll use it some while I learn the angles, but don’t want to get reliant on it either as it makes the process so much slower.So overall, good, and probably worth it - briefly - for a beginner

this is a really great piece of kit for anyone getting started or with experience. it helps keep angles sharp and precise with minimal effort. a must have for proffessionals and learners alike. its compact, easy to use, and will help you re-edge almost anything that uses a wetstone.will even work with metal objects being grinded or sanded with grinders or belt sanders but do that at your own risk as the items originally purpose is for wetstones, not beveling.this item is compact and folds, perfect for any campers or survivalists. definitely a must have for preppers and outdoorsman. may pick some more of these up for family at some point.the simplicity alone makes this a valuable ally for when sharpening or re-edging anything metal

The idea behind this product is great to help aid your sharpening ability at a good cost. The product was well made and fitted to my larger knives well, though, didn't work very well with smaller knives. Additionally, the angle would slip regularly as it was not lockable, so did not work as well as it could.

This makes knife sharpening on a wetstone a lot easier if your not a master at this already.Set the angle, attach it to your knife (Its magnetic) and sharpen the knife whilst watching the spirit level bubble.I tried guides and freehand before and could not get as good an edge on my kitchen knives as I can using this. Its simple and effective.Note, not ideal for small knives but standard chefs knives are ideal.

The one aspect of free hand sharpening that's always got the better of me was teaching muscle memory to remember blade angles, nah I'm useless at it and I am glad I saw a friends using something very similar to this handy little gadget.Setting the device at the angle you wish to grind at and attach it to the side of the knife to be sharpened with it's built in magnets, allow one to accurately predict the angle of attack even before making contact with the stone. Once I'd got the hang of keeping the integrated spirit bubble at a consistent level, the results I was getting were considerably more consistent and resulted in a much finer sharper edge, than I was achieving by free-hand sharpening them.They are injection moulded plastic frames, snapped together and pivots at one end with notches to hold the desired angle. two small slightly weak magnets hold the guide against the knife blade, while one maintains the same angle during the entire sharpening process.Pro's: Great for teaching ones hand the muscle memory required to sharpen knives freehand.Con's: The two tiny ferrous bar magnets could have been stronger neodymium magnets, but they do sort of stay put if you're gentle. I stick blu-tack under mine to be extra sure! 👍

Too fiddly to be of any real use

Some reviews for this are quite bad, but may be they are not usinit it right. I found it really useful . Stick on the blade so as you get a full view of the level, set the angle and away you go, great results.
