Thread: different coticule bevel setting slurries for different grinds of razor?

I was having a bit of a problem with a full hollow razor on the coticule just after successfully honing a quarter hollow sheffield with the same hone without any bother but I could only manage a very rough bevel.

what I noticed was that the bevel setting slurry I used was too thick for the full hollow - even though it was the same slurry (approx.) that I used to set the sheffield razor - so what I did was went straight to the coticule under the tap and after 2 sets of 30 with pressure (both sides) on water it created a very smooth clean bevel on the full hollow.

I was wondering if you guys noticed the same thing with your coticules?

kind regards

Hi Alex,
I don't vary the slurry thickness according to the type of razor (eg quarter or full hollow ground). The less hollow-ground blades often have a wider bevel so they often need more time and attention to get the bevel fully set. So, sometimes I refresh the slurry at the beginning a couple of times before I start diluting to ensure the bevel is fully set.

But in general I try to not getting the slurry too thick and rather refresh or take a bit more time.

Cheers
Jörg

I refresh my slurries as well. the dressante coticule slurry I have is very sticky, I could run the razor under the tap for 10 minutes without removing all the slurry from the edge so I have to constantly wipe the razor after every slurry, same with the coticule.

I've tried to set the bevel 3 more times on this razor and after 5 minutes trying to set a bevel on a milky slurry it doesn't set but a very thin 2% slurry is where it starts to create a smooth bevel in around 3 minutes (dulled on glass) with a near full hollow razor.

It might be that thinner razors sharpen better from smaller particles in a thinner slurry (I'm assuming bigger particles are more common in thicker slurries) but the dressante is performing very consistently now since I've started using thinner slurries for thinner straights.
