The 400 grit peach stone replaced the old 320 in the Edge Pro lineup and is considered by many experienced Apex users to be one of the two must-have stones in the system - the other being the 1000. It sits in a uniquely versatile position: aggressive enough to handle abrasion-resistant stainless steels like CTS-XHP, 154CM, and S30V without the brute force of the 120 or 220, refined enough to leave a scratch pattern that cleans up quickly on the 1000 grit stone. For hard stainless steels in the 58-62 HRC range, skipping the 220 and going straight to the 400 is often the right call - it moves steel fast enough on those steels while leaving less work for subsequent grits to clean up.
One practical note from an experienced user that is worth knowing: these stones behave differently from waterstone bench stones like Shaptons or Naniwas. Speed and pressure matter in a specific way on the Edge Pro - slow down the arm speed and use light pressure, and you can hear the stone cutting properly. Going fast is counterproductive. On softer steels, skip this stone and start with the 600 instead - the 400 is optimized for the harder steel range where you need meaningful metal removal without the aggressiveness of the coarser grits. This is also now the same thickness as the 120 and 220, which is worth noting if you are replacing an older thinner version. Made in the USA, sold mounted to the plate, compatible with all Apex and Professional models.
What Customers Are Saying: Five reviewers gave perfect scores. One calls it his favorite of the standard Edge Pro stones and notes the price at CKTG is significantly better than other vendors - one reviewer paid 40% more elsewhere before finding it here. The most detailed review maps out exactly where this stone fits across different steel types and describes the correct technique for getting the best results - slow arm speed, light pressure, listen for the cutting sound. The consensus among experienced users is that alongside the 1000 grit stone, the 400 is the most useful and versatile stone in the standard Edge Pro progression.
Care Instructions: Rinse after use and store dry. Flatten with a diamond plate when dishing is noticeable. Keep dry between sessions. Use slow arm speed and light pressure for best cutting results on this stone.

Another screaming great deal on this item. This particular stone is perhaps my favorite of the edge pro standard ones. At this price I couldn't refuse. Excellent service from CKTG, order processing through delivery. Excellent packing too.

The 400 grit is a deceiving stone. I believe from EP it now comes as thick as the 220 and 120 stones are. If you are doing abrasion resistant steel, you should skip the 220 and go straight to the 400. With this stone you want to push the stone arm pretty slowly, and use just a tad of pressure. You can sorta hear it when its cutting properly. These stones do not work like shaptons or naniwas, its a pressure/stone arm speed thing. Fast sharpening is counter productive on here. Go slow. The 400 makes pretty short work of CTS XHP, 154cm and s30v. the scratches left by it are very easy to refine with the 1k EP stone. On softer steels, skip this stone and go for the 600 instead. If you are doing harder steels, and you need to remove steel faster, skip the 220 and go for the 120. the 400 and 1000 are the 2 must have stones in my opinion. There is something I really like about the 400, hard to describe! Wish I had it in a bench stone.
