KS123 vs T1 setting

[Malmosyd]

Hi!
I have used the KS123 and my T4 to set an angle of 13 degrees on all my Global knifes. After i figured that i put the angle 13 on my T1 and use T1 as a everyday maintenance sharpener. Is this correct? The setting shouldnt be 26 on the T1 right?  They meassure the same angle if u know what i mean?

Yes, the T1 indicates the angle in dps (degrees per side). So you are correct (see picture).

One word of caution however, the T1 is a constant angle sharpener so you will probably not sharpen the tip of the knives with the T1 if you previously sharpened them following the recommended Tormek technique on the T4. If you want to sharpen at a constant angle on the T4, you will need to pivot instead of lifting, ideally using a laser line on your stone.

Welcome to the forum, Malmosyd. We have always had some confusion with angle terminology. I think the clearest way to describe knife bevels is "degrees per side", sometimes abbreviated DPS).

As for tip grinding with the T1 (and T2, which uses the same knife jig), I understand the reservations, since the design does not allow raising the knife to sharpen the tip of the blade. Tormek has always preached the necessity of raising the knife to sharpen the tip of the blade WHEN USING THE TRADITIONAL SVM AND KJ KNIFE JIGS. However, I can not believe that Tormek engineers just ignored this in designing the T2 and T1. No mention is made of this in any of the online classes.
(I hope this will be addressed in detail in a future online class.)

Of the several critical posts about this, I do not recall any from T2 or T1 owners who have actually experienced this problem.

I am not rich enough (including in kitchen real estate) to buy a T1 in addition to the T8s. Yet I fail to see how owning one (nor Tormek engineers thinking real hard about this) would create a singularity in Euclidian mathematics to the point that a constant angle would give the same results as a variable angle method on every knife.

Widening of the bevel at the tip is a known concern with all constant angle sharpeners, whether belt-,rod- or wheel-based. I own a Global GS-3 where this phenomenon is quite clear, although for many kitchen knives the effect will be offset by the thinning of the knife at the tip. The T8 gives control over this, not the T1/T2.
