Q: How long should I soak the stone before use?
A brief soak of just a few minutes is enough to saturate the porous surface, much shorter than the extended soak some water stones need.

King water stones were among the first Japanese stones introduced to the West. They are aluminum oxide abrasive in a resin bond. In our testing, they were effective in O1 steel but noticeably slower in tough alloys such as A2. The particles fracture and dull after a short period, performing like progressively finer grits, which allows you to move from a medium grit straight to a finishing stone. They are economically priced, require only a quick soaking before use, and are a good choice for honing softer tool steels or when cost is a concern.
These excellent 4000x finishing stones quickly put a mirror finish on tools. The standard stones measure 7" × 2 1/2" and are available as a 1/2" thick stone mounted on an 8" × 2 3/4" rubber-footed plastic base or, for those who store their stones in water ready for use, as a 3/4" thick stone without a base. The large stone is 8" × 2 3/4" × 7/8" thick on a 10" × 3" non-skid plastic base, and is wide enough for even the largest plane blades.
Producing a finer edge than a hard Arkansas, these have the best combination of speed, economy and finish of our fine stones.

Not necessarily, cutting is noticeably slower on tougher alloys like A2, so this stone suits O1 and similarly soft tool steels best.
The standard stone sits on a rubber-footed plastic base for stable benchtop use, while the no-base version is meant for stones kept submerged in a water-storage container; choose the no-base version if you plan to leave the stone soaking between uses.
Yes, these king 4000x water stones carry a grit fine enough to put a mirror finish on tool steel as the final step in a sharpening progression.
Yes, though re-soaking briefly before the next use keeps the stone cutting at its best; storing it submerged saves that step each time.
