One of my Carbon Sabatiers shows an uneven thinning bevel after sharpening. These knives were made in the late 50s/60s so they were hand forged I have tried to work more on the area where the thinning bevel appears uneven I suspect that the surface is not that even is there any way for a question of aesthetics that I can make the bevel straight over this area the bevel appears reduced in this area so it must mean that the surface has a slight depression here . It would seem an awful waste of good steel to take the rest of the surface down to match it would anyone suggest lowering the bevel in this area for the appearance of a straight bevel the effected area is probable about 2-3 cms /1 inch & a bit and it is on one side ? Would it be opening a tin of worms to try to visually correct this the thinning bevel is probable about half the width of the rest of the bevel so down from 3mm wide to just over 1mm wide not including the micro bevel or should I leave it and perhaps in subsequent sharpenings I guess it will probable improve .
As I write I think I am been slightly OCD about it I just wonder if there is a simple solution to this. I have sharpened it with waterstones so the sharpening action is reasonable even since at least a third of the blade is in contact with the stones at any one time.

I'd hate to comment without a picture.

Can you post a picture?

If not, I'll take a good guess.

I and most will need to see a pic even to make an educated guess would due you no justice at all. I love sabatier's but I will need a pic so I/we can tell you properly where the problem lies. Peace, jmbullman

Okay here is a view the primary cutting bevel is fine but the secondary or thinning bevel has a couple of wobbles in it and only on this side.Image

Assuming no user error during sharpening, I'd believe this is probably an overgrind in the knife. When it was ground, more steel was removed at this location than to either side.

I don't know how you'd make the bevel uniform over an overgrind though, well, at least without regrinding the entire knife.

Hi Leo,

Its a bit of a long shot, but its possible that the knifes blade is subtly bent in some way. Might be worth checking before considering grinding it further.
Here is a short vid on the topic. Forward to the 45 second mark.

I have looked carefully at the blade as shown on the link and although the blade is not bent there are some slight hollows in the face corresponding with the undulating thinning bevel so I would say that is a quirk of the knife it is a Sabatier K vintage carbon steel Canadian style hand made in either the late 50s or early 60s with a tapered spine through the handle .
So I guess this is how the thinning bevel will look throughout the useful life of the knife - the primary bevel is true enough - the steel is good - it sharpens easily so I suppose one could describe the appearance as slightly rustic.

Thanks for the link for checking for bent or twisted knives.

Okay this explanation sounds about right since when I checked the knife for twists or bending I saw a shallow were the bevel is uneven .

It was most useful to learn how to check the blade for bends and twists .
