Sharpening Stones
Sharpening stones are the foundation of every edge, the abrasive surface that sets the bevel, refines the scratch pattern, and decides how a blade performs in the cut. DLT Trading stocks sharpening stones from coarse diamond plates for damaged edges and reprofiling through natural Arkansas stones for finishing, in sizes from pocket stones to full size benchstones. The right stone depends on the steel, the edge you are building, the length of the blade, and whether you want a stone that runs with water, oil, or dry. Our knife sharpening guide walks through using them step by step.
Water Stones, Oil Stones, and Diamond Sharpening Stones
Water stones cut fast because the binder breaks down and exposes fresh abrasive as you work, but they wear faster and need flattening over time. The Work Sharp Whetstone pairs 1000 and 6000 grit aluminum oxide on one stone with clip on angle guides. Oil stones, including natural Arkansas, cut slower but leave a refined edge with very little stone wear, which makes them a natural finishing step. The Lansky Soft Arkansas and Hard Arkansas benchstones and the Case Honing Stone Kit, with soft and hard Arkansas stones and honing oil, cover that side. Diamond stones use industrial diamond on a metal base for the fastest cut of any stone type. They stay flat for life, work dry or with a little water, and cut high vanadium steels like S90V and 10V where softer abrasives struggle.
Diamond Benchstones for Bench Sharpening
A benchstone is a full size stone built for stationary work. The longer surface lets chef's knives, hunters, and bushcraft blades run a full stroke from heel to tip, and the wider face handles heavy reprofiling without wearing a groove. The DMT Dia-Sharp Coarse and Dia-Sharp Fine measure 11 1/2 by 2 inches, with continuous diamond surfaces, non skid feet, and USA manufacturing. Lansky Diamond Benchstones in Medium, Fine, and Extra Fine grits carry an edge to edge diamond surface in a self storing case that raises the stone for use. The Work Sharp Benchstone combines 320 and 600 grit diamond with a fine ceramic and optional angle guides, and the Lansky Dual Grit Puck handles axes, machetes, and mower blades.
Pocket and Field Sharpening Stones
Field stones keep a working edge going between bench sessions. The Fallkniven DC4 pairs a 25 micron diamond face with a 5 micron synthetic sapphire ceramic, and the DC3 pairs diamond and ceramic in a stone small enough for a pocket. The folding Fallkniven FS4 Flipstone and FS3 Flipstone tuck their diamond and ceramic surfaces into a handle. The Buck EdgeTek Dual Flat Pocket Stone carries 325 and 750 grit diamond, and the Work Sharp Guided Field Sharpener, Guided Field Sharpener Elite, and Benchmade Guided Field Sharpener put stones, ceramics, and angle guides in one packable tool. For serrations and recurves, the Spyderco Tri-Angle Sharpmaker uses triangular ceramic rods.
Choosing Sharpening Stones by Grit
Coarse grits under 400 handle reprofiling and damage repair. Medium grits from 400 to 1000 set clean bevels and do most routine sharpening. Fine grits from 1000 to 3000 refine the scratch pattern into a working edge, and grits above 3000 polish the apex for kitchen prep and precision slicing. Many stones here are also replacement abrasives for guided sharpening systems. Wicked Edge diamond stones come in pairs from 50 and 80 through 100 and 200, 200 and 600, 400 and 600, 800 and 1000, 1500 and 2200, and 2200 and 3000, plus 1500 and 3000 grit stone and platen sets. Work Sharp Precision Adjust owners can replace the 320, 600, and ceramic plates or step up with the Upgrade Kit, and the Lansky Standard 3 Stone System is an easy entry kit.
