Calibration feature of knife jig

If Tormek decide to make a new knife jig, I want to suggest "the calibration feature"

I think that not only self-centering but also calibration feature are necessary. Because asymmetric bevel(flat grind) or uneven surface of the blade can disable the self-centering.

This can be found not only in knives, which are made very roughly, but also in factory knives produced in the U.S.

I agree with you, Sharpco. I would like to see a much more sophisticated knife jig. I doubt you would find the features you want in a forty dollar knife jig. I hope it will happen, although I would be pleasantly surprised if the design got past the projected market size and price critics.

Mmmmm/ Lets see. Self centering is the most desirable feature we can ask. That will be good for 99% of the knifes.
Calibration of the jig is yet another feature the is very specific and will probably make the jig even more sophisticated at a very high cost. Money, weight, and ease of usage.
"uneven surface of the blade can disable the self-centering." Depend on the self centering design of cause. Do you have an idea for self centering that collided with uneven surface?

I wonder how much would you guys be prepared to pay for a self centering jig or system?

I do not even understand what this is "calibration feature".  Please elaborate.

Quality is like buying oats.  If you want nice, clean, fresh oats, you must pay a fair price. However, if you can be satisfied with oats that have already been through the horse, that comes at a lower price.

Hello WolfY,

IMHO, the calibration feature is more important than self-centering feature. This is because it enables more sophisticated manipulation like a manual mode of camera. 'Automatic' is a good feature but it can't cope with all the situations.

Rick,

It is a feature of fixing the blade with a jig and then manually adjusting the angle using a lever. Would it be better to call it adjustment rather than calibration?

Got your point. Will consider that.

I agree. Rarely is the knife blade centered perfectly in the jig, resulting in slightly different angles on a dual bevel blade.

Agreed.  No question there.  My point in asking was initially simply for clarification of what was meant by "calibration" feature.  Subsequently, once it was clear it was: to further refine/adjust the angle AFTER the blade was held in a self-centering jig, I have two questions, which are really one complicated question. 

If the supposed self-centering jig requires further refinement/adjustment of the angle, then I suggest it has failed in its purpose, and if it has not so failed, then striving for further refinement in the angle is, in my opinion, trying to take things too far - that is, trying to be overly exact in a system that otherwise cannot be that exact. 

Maybe that is really isn't a question or questions..., but maybe it can be stated as such.  If the self-centering jig works, why is it necessary to try to refine the angle any further?

Rick,

The self-centering feature works when only the blade is properly grinded. Check the knives in my photos above.
