From Blum Tool company. The Jig is called the sharpening box.

The Sharpening Box

It is worth going to the web site and checking it out. This is an innovative jig where the blade is fixed and you move the stone across the jig. It’s an approach I had not seen before. There is a informative video showing how to use the Jig. Enjoy.

looks ok, from the looks of it, it has as many limitations as it offers advantages… and costs an extra $150.

I wondered about cambering the blade for example. I would imagine you could do it by eye… What other limitation can you think of?

I guess it depends on how you use it. but in order for the stone to stay at the right angle, it has to have enough contact on the jigs surface, meaning – you only get to use the front half of the stone – and you’d need to turn it around to use the other half of its surface, which might lead to uneveness in the stone, which can cause issues with the sharpening – but I guess thats the same regardless of how you use it – you’d need to flatten the stone from time to time.

a different approach.. need to change the perspective to look at it in an objective point of view.

This is an interesting tool, Wayne. It certainly is a different approach to sharpening.

  • If you like this thing, it would be SO easy to make. Its just a box with a phenolic top and an adjustable front angle.
  • It would be a mess with wet stones. The sludge would drip down the sides of the box and down your chisel handle as well.
  • And for another $50 bucks you could get this (I love my WorkSharp by the way)...

Its interesting but the price point is way off.

-- Happy woodworking!

Great info….I typically find the info more informative then wanting to buy something to sharpen with. Like Purp says….there is always some plus…and some minus….but the cost of these items is prohibitive to their benefits. So far I have found that diamond and or water stones…patience and a strop does what all these machines do for a fraction of the cost…..but I have practiced this and perfected it to my satisfaction…others may find a machine more to their tastes and I certainly have no beef with that….to each their own and if it works for them…thats what is needed.

I’ve looked at that a couple times and IMHO it’s a neat setup if you’re using oilstones or diamond stones. But you’d lose any slurry needed on the waterstones, not to mention making a heck of a mess.

Yet another sharpening gimmick! I cannot see any real advantage of this system over any of the others out there.

I am sure that the phenolic top will require flattening from time to time, as the abrasives hollow it out. The clamping screws will soon need replacing as they become worn with all the clamping and un-clamping that was going on in the video.

As blake says, for a few more $ you can get a Work sharp or a TORMEK “look-alike”, both of which are more versatile and significantly faster. Even using a $30 honing guide and some Wet & Dry paper is significantly faster and equally as good as what was shown in the video.

Learn to use the old fashioned method, its fee of gimmicks, cheaper, faster, you will get a better edge and it is certainly more satisfying.

I’ll stick to my grinder to get close to the final edge, then use my grinder mounted 6” mdf wheel with rouge to get scary sharp. I’m not a fan of gimmicky sharpening systems.
