Reddit mentions of Sk11-sided Diamond Whetstone # 150 / # 600

Do you know what they currently have at all?

A really coarse stone with another side for finishing on would be this - useful for fixing chipped blades and overall getting a very sharp edge. It's diamond so it does not need maintained. It's quite heavy so it can be set down on something and used anywhere with a splash of water, or even without water. But better with..sorry it exceeds your budget a bit. It was 7$ cheaper a few months ago: Sk11-sided Diamond Whetstone # 150 / # 600 https://www.amazon.com/dp/B003EIE8LC/ref=cm_sw_r_cp_apa_i_K765Ab44NE259


A good at home stone in your price range would be this one, you have to soak it in water for 5-20min before using (each time, until it stops bubbling in the water) but it's a great stone that is widely used: KING KW65 1000/6000 Grit Combination Whetstone with Plastic Base https://www.amazon.com/dp/B001DT1X9O/ref=cm_sw_r_cp_apa_i_n565AbSFCV7EG

Anything 'bearmoo' or 'sharp pebble' or anything looking like those ones honestly is not going to be enjoyable or comparable in quality to the above.

Another great stone worth mentioning: Shapton Ha No Kuromaku Ceramic Whetstone Medium Grit #1000 https://www.amazon.com/dp/B001TPFT0G/ref=cm_sw_r_cp_apa_i_o-65AbB1PMZ8B

If they already have some bench stones, maybe they can use a holder - super useful!: POWERTEC 71013 Sharpening Stone Holder, 5-1/2-Inch to 9-Inch https://www.amazon.com/dp/B00NFB2MTI/ref=cm_sw_r_cp_apa_i_h.65AbP2HAJ5W

After that new king wears away you guys can probably invest in a slower wearing Shapton Professional as well as a cheap lapping plate.

I just got this Sk as a cheap lapping plate and was surprised at how much my 1000/6000 king stone dished.

Do you guys work in a butcher shop or something?

The Naniwa Combi 1000/3000 is splash 'n' go, compact, and cheap. Pair it with a King Deluxe 300, Shapton Kuromaku 320, coarse diamond plate (I like SK11), or Norton Crystolon JB-8.
