SLIVERAX — ELEGANT DREAMED ENGINEERED KNIFE – ACT II: Convexing.

Many times, people asked me how I was honing my knives to my taste.
I love thin edges and I love edges which can be maintain by stropping on leather.
For that any sharp angle but the edge itself need to removed.

So my first step on the Sliverax full flat ground blade is to remove the shoulder on the secondary bevel. For that I use Fallkniven FB04 diamonds or Spyderco Double Stuff II.

As I don’t want recreate two other angles, I do it free hand creating a gentle natural convexed medium between the grind and the edge.

Soo some dark dust of removed metal appears. The edge of the blade is untouched as after some initial testing I do trust it.

I need that convexed edge on the belly of my blade, I don’t minde about the tip and the choil which are not where I do apply the most force to push cut through wood for example. It takes 30 minutes to get where I want without to make a mess by scratching the blade finish. It means each pass on the diamond is check with my finger before, sto be certain to focus on that edge shoulder. To obtuse it will scratch the edge and to acute it would scratch the blade finish. So it takes time to be certain for each stroke.

Luckily the manufacturing lines on the blade exactly follow my pass and some miss strokes were not visible.  It takes around 500 passes on each side on S30V.
Then I switch to white ceramic directly.

White ceramic brings some mirror polish on the convexed edge and also hone it to razor.
Here I can go much faster as I won’t ruin my blade if I’m clumsy. White ceramic are very forgiving…
Soon I got a very nice mirror on both side and I can go to leather.

I use a century old barber accessories I have found in a garage sale in Italy. With some white compound, it has honed my blade for 15 years.
Time to test the blade on a chesnut road.

The thinner edge goes much more deeper and with more control and more ease.
Eventually after playing with the knife for 5 minutes on various material, I inspect the edge and there is no chipping or rolling.
It takes me around 45 minutes.
That’s how I proceed to get an edge which suits my need. 🙂
