General Tormek Questions / Re: the missing knife test

This topic needed to be revived. It is very useful for knife sharpeners, with some much needed, solid advice. I also had a good laugh reading koolingit's delightful comment.


General Tormek Questions / learning curve revisited
« on: Yesterday at 07:46:57 am »
We have frequently discussed the learning curve in the past. I believe the flexibility of the Tormek allows the user to choose the amount of learning curve to suit his needs and wishes.

A Tormek user who wants to keep his home workshop chisels and planes sharp using the standard SG grinding wheel has only a short learning curve to master. Adding the family kitchen cutlery, his pocket knives and scissors adds only a little more learning.

Adding a larger variety of tools, including tools with different steel, adds to the learning curve. Adding the more stringent customer expectations and volume of business definitely increases the skill level required, as does using multiple grinding wheels.

Harnessing the exciting potential of the three diamond wheels and multi base will certainly require more skill. We will have to learn new techniques as well as developing a lighter grinding pressure. We will have to factor in flat grinding in addition to our traditional shallow hollow grinding.

We have choices. A sharp tool is a sharp tool, whether it is sharpened using the latest diamond wheel or the standard SG. The basic technique and SG grinding wheel have served Tormek users very well for decades, and will continue to do so. While this path remains a viable option, it is no longer the only path. Today's Tormek user has choices which were only imagined not too many years ago. We live in interesting times.

I found Terry most informative.

General Tormek Questions / Re: DWC-200

Interesting thoughts, SADW. You bring the perspective of actually being in the restaurant into the discussion. I would not have thought of bacteria in the water trough. I agree with you about the consistent diameter and the the general need for touch ups rather than damage repair.

I have mixed (and not totally informed) feelings about the rubber honing wheel. Until the three new diamond wheels were announced, I was convinced that the T4 was the ideal choice for many operations. I will be interested in following developments in Tormek honing. My gut feeling is that after the dust settles with diamond wheels, Tormek may turn the big guns toward honing (or knife jigs :)  )

For the record, I happen to think the T2 is well designed for its niche market, being used by restaurant personnel rather than by sharpeners.

Interesting thought, CB. I hope we can look further into this.


General Tormek Questions / Re: Diamond wheels vs grind stones
« on: March 17, 2018, 01:58:20 pm »
I would like to begin to add my two cents to a few of the many good areas this topic addresses.

First, instagram videos. I confess total ingorance concerning instagram (and facebook). That's my problem. I have a big problem with useful videos which disappear. There was supposedly a one day wonder video on instagram about the new Tormek diamond wheels and multi base. Not being an instagram user, I missed it. I have heard that it was very informative, more so than the material posted on the Tormek website. I have no problem with posting videos on instagram or facebook, however, why must this be an either or situation? I continue learning from you tubes made by Jeff Farris in the SuperGrind era. If a training video disappears after a day, why bother?

Incidentally, if you could pm me a link where I could watch your videos, I would enjoy watching them.

Now that I am off of my soapbox, I would like to mention hollow grinding. Many years ago, I used my six inch dry grinder to create hollow grinds and switched to stones with the two contact points and microbevels. The small grinder creates very visible hollows. In theory, the larger Tormek wheels do,  also. However, in my opinion, the amount of hollow from the large diameter wheels is negligable.  I mention this in the spirit of conversation, not debate. I would welcome your thoughts on this.

Duty calls; I must close for now.

Another valuable topic which should be reread.


General Tormek Questions / Re: Honing

I found this topic, and realized that it contains a lot of valuable information, and needs to be resuscitated.

I was also pleased to find Rick B., an active member since 2006. Rick, you are a refreshing rebuttal to the argument that members join only to ask one question and then disappear. (You have been a member for three years more than me.)

Incidently, in later posts you asked about sharpening metal lathe bits. That area is evolving and should be accelerated by the new side grinding diamond wheels and multi base. Pay attention to the posts of Rick K. He is a machinist, and I believe will be a leader in the movement to include sharpening metal lathe bits with the Tormek.

Keep posting!


The old reliable Tormek SuperGrind (SG) wheels can tolerate a lot of abuse. Many are still in service even though being rusted to the pre 2006 non stainless steel shafts. Many are still running which have not been kept true and dressed.

These old troopers are like the phoenix; a session with the truing tool can restore trueness and expose fresh cutting grains to the surface.

As we enter the world of Tormek sharpening with diamond wheels, we also enter another learning curve. We must unlearn our aluminum oxide (SG) habits. Reexamining how I used the DWC-200, which I really like, I realized how deeply engrained my aluminum oxide habits are. With AO, the surface finish is visibly improved by using a very light touch with the last few passes. With diamond, the entire grinding process should be done with light pressure. Diamond is both hard  and fragile. Used carefully and correctly, a diamond wheel should be a lifetime purchase for most of us.

In my subconscious mind, I can visualize Jeff Farris lifting one side of his SuperGrind with grinding pressure on his chisel. “Don't be afraid to really lean on it!” This works with AO wheels like the SG. No doubt it also appeals to the younger, macho, prospective buyers. (To keep this comment in context, I must add that Jeff also stated that the Tormek also works very well with a light touch, such as someone with arthritis might use.)

Once the AO grains eventually became dull, the truing tool can remove them and expose fresh new (sharp) grains. Granted that the diamond wheels have exceptional endurance, perhaps more than the operator, if the diamonds are dulled due to misuse, there are no new fresh grains to restore the wheel.

We must learn diamond thinking. We must let the extreme sharpness of the diamond grains gently do the work. My DMT diamond flattening plate is a constant reminder of that. It was hyped as being able to flatten any stone in the shop. The hype is almost true. It excels with waterstones. It not only flattens AO oilstones such as India stones, it restores the sharp cutting surface, making them cut like new again. However, it is no match for crystalon stones (often an alternative for AO, especially in coarser grits). An old crystalon stone ruined my $200 US diamond flat plate.

The plate is a good and useful product. I give it high marks. I do not extend these high marks to the company marketing department or the enthusiastic reviewers who did not shout the caveat. (I have not used my plate for several years; marketing may have corrected this situation by now.)

I do not want Tormek diamond wheel users to fall prey to the same lack of knowledge. In fairness, I have seen the grinding pressure quietly mentioned by Tormek. However, this is not enough to counteract long developed SG working habits. This caveat needs to be bold and frequent. My initial use results with the DWC-200 and DWF-200 have been very positive. They are wonderful new tools which will revolutionize the Tormek. However, retraining is essential for these fine products to shine.  I hope Tormek will have outstanding video training on the website before these wheels are available in June.


Knife Sharpening / Re: Tilted collar of knife jig

This topic is a little heated, which is very rare for this forum. We are a group of civil, helpful people who take sharpening very seriously. I believe you have already met Stig, the head of Tormek support. This situation with the knife jig will be resolved. I have complete confidence that oir ship will soon be restored to an even keel. We have no prima donnas here; we work as a team to solve problems.

Welcome, Tom.

Thank you for a thoughtful post. It will take me a while to digest.  :)

I thought so, too. However, Stig sent me an email requesting that I delete the reply as it was not the issue and it would cause confusion. I know and respect Stig enough to know that his request was honest.

Due to the shipping distances involved, fully resolving this may take some time. I have no doubt that it will be resolved.
