DIY Sharpening System For Knives

Learn how to build a DIY Sharpening System for Knives with a step-by-step tutorial, measurements, and video. A perfect project for woodworking beginners.

Have you ever thought of sharpening your knives, scissors, chisels, or woodworking planes at home? Well, I have… I must say, I am no sharpening master but having a sharpening jig at home is definitely handy. So I decided to build this DIY sharpening system for knives.

The 3 main components of this DIY sharpening system are a larger plastic box, a smaller plastic box, and spruce wood slats. You can easily get below 20 dollars for the material (not taking into account the price for the whetstone).

The sharpening station is portable and you can easily use it on a benchtop. The station contains a sharpening table and another smaller box for water and whetstones. Also, the sharpening table is removable from the box and can be used separately.

If not used you can slide the whetstones under the sharpening table (or in the smaller box) and close the station with a lid. The station is equipped with an adjustable slider that will let you fix whetstones of different sizes up to 20 cm in length.

This is a very beginner friendly project requiring very basic tools. Check out the jigs I used to build it (see at the end of this post).

With the instructions in this blog post, you will learn step by step how to make a DIY knife sharpening jig. I hope you enjoy it! Let’s build it!

How hard is it to build?

Not hard at all!

This is an easy project for beginners requiring very basic tools.
The project is straightforward and the cuts are simple. You can build the entire sharpening station in a day.

This would make a great weekend project.

Do you need a lot of tools to build it?

Nope! Just a few basic tools.

  1. Hand saw (or a jigsaw)
  2. Power drill
  3. Drill Press (optional)

Let's Start

How To Make a Knife Sharpening Jig

The entire sharpening system consists of 3 main components:

  • Larger box – contains a smaller box, a wooden slats table used for knife sharpening, and a sharpening station (base) on which stands the table 
  • Smaller box – used for water and soaking whetstones
  • Wooden slats table – made out of spruce wood. Includes a ‘pocket’ for storing whetstones

I got the boxes from Ikea but I am sure you will be able to find some in your local hardware.

Just make sure that the total height of the sharpening system with the set grinding stone is higher than the top edge of the box. Thus when sharpening, you will have enough space around the whetstone and you will not hit the box with a knife. And when finished you can store the stone under the sharpening table and close the entire sharpening system with a lid.

Build a Sharpening Station

The main purpose of the station is to lift the sharpening table and at the same time to serve as a base that fixes the table in position. 

To build the station start by measuring and cutting all the wood pieces (see all dimensions above – Sharpening station). A hand saw will do just fine.

Cutting wood for a sharpening jig base

Place the wooden guide rails in the box, adjust as necessary and take into account the width of the second smaller box so that both fit nicely.

Fix the guide rails with smaller wooden slats using wood glue. Additionally, you can run several screws in.

Temporarily fix the station in the box with double-sided tape and then run several screws in from the outside of the box to make a permanent fix.

Make a Wood Slats Table

Place in the second box and cut the length of the table legs accordingly so that the table fits in nicely. 

Place the legs on the station right next to the base stoppers and start gluing wood slats on the top.
I am using wooden dowels as separators – 10mm and 6mm.

Additionally, you can fix the sharpening table slats with countersunk screws.

Glue a wooden bar at the top of the table that serves as a stopper for the whetstone.

Make an Adjustable Bar

To secure the whetstone from the bottom of the table I made an adjustable bar that runs in the slots between the wooden slats.

Drill a hole on each side of the bar for a ø6 mm bolt. Use a drill press table to make accurate holes.

Measure the distance between the holes so they match the slots on the sharpening table. Insert temporary bolts in and place the bar on the table.

The bolts will be replaced with wooden star knobs later on.

The second bar fixes the first one from the bottom of the table. Drill a shallow hole on each side of the bar using a 15mm Forstner bit (to sink the T-nuts), drill 2 (7,5mm) holes in, and insert the T-nuts.

They should be flush with the surface.

Make Wooden Knobs

And now the star knobs.

To secure the adjustable bar I made 2 wooden star knobs that replace the temporary bolts.
Specifically, the bolts are inserted in the star knobs.

To make the knobs I used a Star Knob Jig I built some time ago – check out the post here – How to make Star Knobs with a Kob Jig

To make a knob cut out a circle with a saw hole. Insert it on the knob jig and drill out a star knob.

To sand the edges I mounted the knobs on a drill press and smoothed them using a sanding wheel. Drilled a 10mm hole in using a Forstner bit and carved a hexagon to sink the bolt’s head.

You could add epoxy/glue to fix them but there is no need for that – they hold up very well on their own.

Finally, I assembled all parts together and the sharpening system is ready for use.

How To Use The Sharpening System for Knives

One of the biggest advantages of this knife sharpening jig is that you can use it as a complete sharpening system having all the components stored in one box – sharpening table, box for water, whetstones. Or you can use it separately by taking out the knife sharpening table and use it on its own.

To use the knife sharpening system first mount the whetstone right up to the stopper and secure it with the adjustable bar. Whetstones of different sizes can be used. If built correctly the height of the whetstone should be higher than the upper edge of the box.  

The smaller box can be used for water, soaking whetstones, or as additional storage. You can also store more whetstones under the table slats.

Once done with sharpening you can simply put everything back in the box and close it with a lid. A very handy and useful small workshop organization idea.

This was a fairly easy project.  It was really fun to build and the wooden slats table looks just great.

Having a sharpening system in the workshop is a huge benefit. I can use the station any time I need without making a lot of mess around. Now, I just need to improve my sharpening. 😉

So.. Ready to build a knife sharpening jig? Let’s do it! 

HAPPY BUILDING!

Build a knife sharpening jig and easily sharpen your knives at home. With this knife sharpening system you can also sharpen chisels. It is an easy woodworking jig for beginners.

The main focus of this article is on how to build a knife/chisel sharpening jig and does not go into detail on how to sharpen them. I would like to write an article in the future dedicated only to that.

I hope the information shared in this blog post inspired and now you are ready to make your own home knife sharpener. Or at least thinking about it! 😉
