Born from the need for improved light, compact and versatile edge sharpeners for uses from home or workplace to remote wilderness.

In bright easy to find orange and pocket sized only approx 14 cm long. 65 gms light weight due to the handle is hollow.
Diamond stone surfaces approx 75mm x 30mm.

ALLHONE twin Angle Sharpener handle has opposing flat surfaces that consistently align a blade angle and this speeds up resharpening.

• Options; 17.5 deg for around 2.5 mm spine farming/butcher knives of Victory, Victorinox, Swibo etc.
• 15 deg for Mercators which have a 3mm wide spine.
• 12.5 deg for 4 to 5mm spine or have a bevel, usually high end Italian folders etc or survival bush ones like our Manly Eagle.

240 and 1200 grit is a common combo for what is known in the sharpening fraternity as a work edge a hunter will love.

180/1200 grit stones are sold by Mercator Germany for their knives.

We supply 240 grit and if that still sounds too coarse for you well let me explain that diamond stones including expensive USA ones quickly lose the outstanding grits as they get knocked off and lost creating a more uniform level field of grit height within a few resharpenings and produces what is known as a working edge, toothy just like a steak knife on a micro scale.

You will get shaving sharp on the 1200 stone gauranteed.

We also offer it in 1000/3000 for those that like doing extra fine edges in the 15 deg for low angle.
Not sure that you are resharpening at the best angle every time? This tool fixes this problem without the need of complicated devices to help you achieve a consistent resharpening angle and save time in the process instead wasting time removing shoulder steel instead of sharpening the actual edge angle.

Simply lay a flat side of the blade onto to the flat handle surface adjacent to the diamond stone to set the angle for resharpening the blade edge. Then move the blade edge on the stone's surface in a rotational motion and relay the blade onto the flat surface to re-align the degree and repeat motion until resharpened.

Before use, spit on the surface. When finished simply wipe clean the surface with a cloth to remove the fines created during reshapening.

Recommend 5 times both sides of the blade's edge on coarse and then do repetitive sets of 5 times both sides until removes hair on arm.By counting only five you don't develope a bur on one side and stop before you over do it. If you do get a bur then go back the the coarse stone and remove the bur. If it is leaning over to one side just rub that side.

You can calculate the apex angle of any blade at the above. Enter your blade measurement from edge to spine as leg (if your blade is not a flat grind and is a bevel type estimate the spine width by eye off the flat surfaces) and enter the spine width as base and it will automatically calculate the apex angle as vertex angle.

Mercators and folders usually the 15 deg for the farming blades where the blade's around 2mm spine and longer leg distance from spine to the edge so around 30mm the 17.5 is fine. Knives with a bevel and or wider spine around 5mm thick the 12.5 deg.

ALLHone Angle Guide Twin Diamond Sharpener will produce a good clean and efficiently sharpened edge with a little practice. Repeatable in the field without complicated apparatus.

Mercator factory is at approximately 20 degrees compared to the two resharpened in the image. Google AI and others say is 10 deg which is incorrect as illustrated by the image of the three.
