Diamonds are forever

[Anonymous]

As Waka can attest, my DMT duo works great after about 3 years as my primary flattening and sharpening stone - he kindly sharpened a few of my planes on it recently

Nothing lasts forever, but good quality diamond stones seem to last a fair while and are good value for money IMO

Had trouble: Yes
Sort of trouble: Diamonds dropped off
Type of stone: Trend 7" x 2-1/2" double sided bench stone (coarse side)
Lubricant used: 'honing fluid' supplied with the bench kit (WD40 with blue food colouring in it if you ask me!).
Usage: Occasional flattening of tool backs, grinding of primary bevel on chisels and plane irons. Light pressure used.
