Small but effective.
I thought the price for this brand was roo good to be true. These are small. Just, and I mean just big enough for most chisel, but plane blades will need something larger. These do sharpen enough to cut hairs off the back of your hand. Perfect for pen knives. I'll have to save my pennies for the larger ones.

Made in USA but quality control meh…
Expected to be finished to a better standard considering the brand and “made in USA” complete with flag on packet…”Quality must be manufactured, not fabricated” … yeah right…will see how they last..and if worth the extra expensive over Chinese made competion (ps, Amazon delivery getting poorer, dumping or else wrong postbox etc, etc)

Sizes are miles out should the description by in MM not CM?
These are tiny, I really have no idea how they get the measurment to be those quoted on the site, I suspect that 27.5 should read 2.75 MM!!!

I sharpen skates with a Sparks sharpener and use these stones to deburr the skates afterward. They are the perfect size and very comfortable to hold. I mostly use the blue one, finish with the green one, and keep the red one in my hockey bag for pre-game touch-ups. These stones have become an essential part of my skate maintenance routine.

Ideales para poner en marcha un filo que esté ligeramente dañado o embotado y rematarlo. Luego se puede pasar por el cuero para acabar de pulir las rebabas A la hora de afilar uso limpiacristales o agua y siempre con pasadas muy, muy suaves porque comen un montón, sino en cuatro días se quedan lisas como un espejo. Para limpiarlas uso una goma de borrar normal del cole Tengo otra de esta marca de dos granos, le he dado mucho trote, con ella he aplanado varias piedras naturales, un par de chinas y dos cerámicas, he afilado una navaja en acero carbono D2 y aún sigue comiendo bastante. El truco es lo que he dicho, apenas hacer presión y que vaya comiendo material, se marca el filo con un rotulador permanente negro y se va viendo como va quedando..tenía una navaja Timberwolf D2 mellada en dos sitios y usándolas por fases y luego puliéndola en cuero con pasta ahora vuelve a cortar el papel de tiquet de hipermercado Al principio necesitan un tiempo de rodaje, porque al principio vienen muy ásperas, luego con el uso se van desgastando algo y el acabado es más fino (menos rebaba), asi que si al principio los resultados son algo bastos...sigan usándolas. Al revés que con las otras piedras, cuando llegan al final de su vida y se ha desgastado del todo el abrasivo se acabó, pero bien cuidadas pueden durar mucho tiempo

Only got 2 of 3 stones as many others. How hard is it to send a complete set?
