Credit Card Diamond Stone 300/600#

Freestyle Recess with Innovative Handle Design


New and Improved
The Credit Card diamond stone is a handy little sharpener, successfully used for years by woodworkers, crafters through to other groups such as fishermen and gardeners. The perfect size of Diamond Stone with some great improvements.

The Recess Design:
This striking new design helps draw the debris filled lubricant away from the abrasive surface of the Diamond Stone, unlike so many others.
The distinctive look of MPOWER’s “Free Style” Credit Card will leave you in no doubt that you made a wise purchasing decision.
Our new Free Style range offers extraordinary durability and will become your default diamond stone for all your router bit and saw blade sharpening needs.

Get a Grip
It’s the first Credit Card Diamond Stone to incorporate a handle. It sounds obvious, but by not having a handle, the user has to hold the stone by the same surface that the tool is being sharpened on. One slip and the first thing the tool tip or blade edge could meet is the hand that’s holding the stone. So it’s safer than before. And for those who like to use a lubricant when sharpening be it a lapping fluid or just water. The handle keeps the fluid on the cutting surface not on your hands So there’s less mess.

Sharpening Clearance:
MPOWER’s Credit Card can also be Bench Mounted using the new DSH Diamond Stone Holder (optional accessory), which simply interlock to provide a stable non-slip surface whilst also providing sharpening clearance from the stone to the work surface.

The Credit Card is one of three designs designated as a GPS – General Purpose Stone. Denoting its versatility in being able to sharpen a huge array of tools.

It also gives much needed elevation allowing the handles of knives etc to comfortably clear the work surface when sharpening. The Diamond Stone Holders – DSH can also hold a range of other manufacturers Credit Cards and larger solid Bench Diamond Stones. (not included)


Kitchen Knives
From a large carving knife to a paring or filleting knife – The Credit Card can cope with all sorts of different sizes and knife styles.

Drill Bits
A lot of people (sadly me included ) treat drill bits as disposable items, they blunt, you throw them away. Its only since being a part of the team that researched and developed the new Diamond Cross range did I discover how easily Drill bits of any size can be brought back to life with a few strokes on a diamond stone.

Craft Knives
The “snap off” blade craft knife is a really useful addition to the tool box however it’s made all the more useful by sharpening and re-sharpening the blade. There’s really no need to snap off an old section of blade. A couple of sharpening strokes on the Credit card stone and it is so much sharper than even a new section of blade.

Our research uncovered the fact that the poor old scissors were treated in the same way as Drill bits and Craft knives. They were disposable. They go blunt and you throw them away. Now having tested the Credit Card Stone over a few months I’ve sharpened every pair of scissors in the house. That’s 2 x pairs of kitchen scissors, Hair cutting scissors and clippers and a pair of office paper scissors. Each pair are now cutting so much better than even new.

Garden Shears
The Credit Card is equally at home sharpening tools in the garden. Again the surprising result of our research is that it simply doesn’t occur to people that their secateurs, hedge clippers, shears and edge trimmers don’t need to be sharpened by professionals.

Saw Blades
Both Tungsten Tipped blades and High speed steel can be sharpened using the Credit Card, however based on personal preference I would recommend using the Router bit sharpener stone. It’s not as wide as the credit card stone so it’s easier to maintain contact with the face of the saw tooth for the full sharpening stroke.

Small Flat Bladed Screw Drivers
Electrical screw drivers need the tip kept square to help prevent damaging the slots in the heads of the screws. Which is an easy task on the Credit card stone; a few sharpening strokes with the tip of the screw held at right angles to the stone surface and the drivers good to go again. (we do suggest using the Diamond stone holder for this operation)

Small Carving Chisels Gouges
Anybody well practiced in the art of hand carving will already have the knowledge and skill set to keep their chisels sharp, probably with a range of different sharpening stones. However the Credit card stone is uniquely stable when used with the Diamond Stone holder. So it’s great for the smallest of gouges. A great stocking filler for the woodworker with almost everything.

FAQ, Hints & Tips

Bedding In
All new Diamond Stones feel very coarse to the touch regardless of the micron or grit size of the Diamond used. This is a result of the plating process and is quite normal. After the first couple of times being used. The stone will bed in and the difference in grit will become more apparent.

No Pressure
Guilty as charged, I have always used too much pressure when sharpening on Diamond Stones. It is absolutely the case that an easy light pressured sharpening stroke is all that is required to gain optimal performance from any of the Diamond stones. To use too much pressure can tear the diamond particles from the nickel bed – compromising the performance of the Diamond Stone and reducing its serviceable life dramatically.

Again it’s really down to personal preference as sharpening stones can be used dry. We do recommend using a lubricant. Water works well or a purpose design lapping fluid but really it’s down to personal choice.

Dangerous Tools
Warning by the very nature of the tools being sharpened i.e they are ALL designed to cut something. They can be, in the wrong hands, very dangerous especially for the young, inexperienced or untrained. We highly recommend only experienced users attempt to sharpen tools.
