M398 is a fragile steel compared to M390. The encounter of the tip of the Roadie XL with a tile of my kitchen has been definitive. One mm has been shattered and now I got a micro flat screwdriver as a tip.
OK. Diamonds are steels best friend.
I’m able to form a new tip in a diamond shape.

For now I won’t baby that Roadie XL anymore. I decide to thin the edge.

The best way is to protect the blade to avoid any big scratches.

Then it is time to play with industrial diamonds.

I will also use some diamond rod to round the jimping.

Of course I’m enough clumsy to scratch the blade twice and I’m obliged to use some diamond paste to treat the surface.

Then some polishing paste on the leather to slowly makes it like a mirror.

I’m quite happy with the result.

Time to test this new geometry. The edge has been convexed and thinned it should cut much better.

One of the most difficult task is to cut in two the butt of a two liters plastic bottle. This is a test my Scandi blades fail all the time. Any Opinel is king in that. Or the Manly Wasp ! My favorite being the Nilakka.

As a whittler it goes deep in wood.

As a steak knife, the shape of the blade brings only the new tip in contact with the ceramic of the plate.

That new tip is strong enough to be able to pierce a metal lid of a green bean jar. A hole pierce help the release of the lid on some jar.
No damage no more.
Now the Roadie XL cuts much butter.
