Question: Are these the 1/2x12 belts? amazon is off on the size!!!
Document: These belts do a great job of honing your final edge, unless you are like me and finish with the leather strop, and whatever  the compound is needed. These are good belts they seem to hold up very well!! sure you will agree. thanks work sharp and amazon  Pitbullman
I love the simple use of this product. I use the Work Sharp on all types of sharping knives scissors and other product. i demonstrated this to our boyscout troop at a meeting. Some of the fathers said that they were going to buy this item from amazon. I have used Lansky and other types of electric sharpeners but this is AWESOME.
This knife and tool sharpener is easily one of the best items I have ever purchased off of Amazon. I have been frustrated for years with dull knives. Kitchen knives, pocket knives etc. I have bought wet stones, diamond sharpeners, files, etc. and have never been able to CONSISTENTLY achieve a good sharp edge; much less a razor edge. Within 10 minutes of receiving this product, my problems were forever over. Is this hyperbole, gross exaggeration, paid comment,  NO WAY.
Belts for nice sharpener
These are what you have to have for the tool they are designed to fit. Can't sharpen with old belts.
I am not impressed with these belts because the belts do not last long and do not sharpen the knives well.
works great with sharpener, should offer a discount if buying more than one box of belts in the same ordere.
The Work Sharp would be useless without belts so we wanted to be sure and have a good supply on hand.
Not that you wear these belts out to quick,but I am one of those folks that always likes to have spare parts. Thanks.
Easy to use and puts a sharp edge on my knives. Belts are easy to take on and off and last quite a while.
Answer: yes
