Knife sharpener - Wusthof whetstone

Custom made for my Wusthof whetstone (ref 704773), here is my sharpening device !

Inspired by some i found here, i made my own, according to my tastes and needs.

I purchased the stone online on knivesandtools (24€ + shipping) , very happy with it, but wanted to be more precise while sharpening my knives, so ... here it is.

Stone sizing : 150mm x 50mm x 24.5mm

Tube used : 10mm aluminium (pretty close to 3/8 inch)

Bolts used : M5 (and the nuts fits tightly, no need to glue them) and small wood screws for stone holder.

Magnet used : 10mm wide, 2mm thick. (a bit tricky to fit them, but once in place they won't move.)

You'll find two "angle parts", 20 and 25°.

It'll help you calibrate the device for the angle needed.

(Knives are usually sharpened between 17 and 25°, depending on the origin and need of sharpness. The thinner the angle, the sharper it gets, but wear faster)

I uploaded all the STL files, as well as the assembled part : don't print it !

You wouldn't be able to use it ...but could be helpfull to help you figure out how to make it work.

Feel free to ask anything, i'd gladly help !

And ... please, don't forget to wet your stone before using it.

It's a whetstone, it's designed to be used with water. Not dry.

If you ain't sure, have a look online, there is lots and lots of informations on the process !

Cheers !

[UPDATE]

Following request, i added a 35x25mm stone holder !

[UPDATE]

• A bit of clean up in the files / names, should be easier now.
• Added a 17° angle calibration part
• Updated the two slider parts, after mine failed. I made a larger hole, so it's easier to use; and made the parts sturdier.
• I added a small 8mm hand knob, to use with M5 hex screw. This way, i can adjust the height of the slider, and the retainer,without tools.

[Update 24/04/2025]
 

• Added a 59x29mm stone holder
• Added a parametric stone holder file (*.F3D) so you can make it your own (but i'm always done  to make it to your liking, don't hesitate to ask !)
• Added a 10° and 14° angle adjuster
• Added a parametric angle adjuster, with parametric text on it, so you can make your own angle, according to your liking, or the brand's recommendation (but yet again, feel free to ask for help)

Cheers !

Notes:

I printed it with variable infill, 20% for the first 2mm, then 8% for the rest, and again 20% for the last 4mm. rnI made this because of the holes in the big part; and s3d didn't manage it well.rnrnPrinted in black PLA, on my i3 mk2s, great result.rnUsed raft, but i don't think it's mandatory.rnEverything can be printed without supports.
