Naniwa Gouken Curved Water StoneA Water Stone for Curved Blades Water Stones have become a favorite of sharpeners in search of the best edges. But previously, sharpeners working with curved edges like those found on pruning shears, florist's and grafting knives, and hawksbill knives have had to work mostly with flat stones, and anyone who has tried to sharpen a concave curve on a flat stone can attest to the difficulty that presents. The Gouken Curved Water Stone neatly solves that

Not what ad picture promotes - just patches - no more
Size: 24 x 35mm
For twice amount of money that other tire kit repair offer - it has no glue, no lighter fluid, no scratch tool - just top $ for patches. Show in video how to fix, but after you get it you'll find that you need to go back online and order, glue, lighter fluid, scratch pad, and perhaps even a roller tool. Just order a kit with needed accessories & patches to start with at half the price.

Rectangle shape covers & adheres well.
Size: 24 x 35mm
This is a rectangle shaped patch that I prefer over circular patches. Covers well and gives new life to inner tubes on the used bicycles I repair to give to charities.

Just the patch, nothing else
Size: 24 x 35mm, Size: 24 x 35mm
Tried this with cement glue for PVC piping. Not sure if they are a different type of glue. The patch didn't stick at all. The instruction says to use lighter fluid, which I didn't have. Very inconvenient to need all sort of stuff to just patch a few dollar tube. I was hoping a simple process of removing the cover and sticking it on the tube. Several hours of waisted time.
