Old Timer is 1095 Carbon, and I am curious how you approach not only this steel, also the blade shape in sharpening.
To best answer your question I need to define where I am in the world of cutlery.
A "sharpener" does simply that. Big ugly rock rubbed on a knife.
A "polisher" is a usually a trained Japanese craftsman who does historic appraisals and documentations, repairs and 'polishes' what we would consider the edged weapons of the samurai. In this pursuit, he uses traditional Japanese style polishing stones, historic and stylized training and methods.
I am a "tinker." Yes, the bulk of my day is "sharpening." But in providing that service, I also repair and salvage knives, tools, pots and jewelry clasps. I have chosen to provide the best service I can by studying and duplicating as many of the polishing procedures I can in a Japanese understanding.
To accomplish this, I seek out tools and systems which are simply a modern rendition of the Japanese idea. I might use a stone from Edge Pro, and a paste from Hand American. I might polish with a .5 micron paper from 3M, using an application of pastes and oils secured to a thick piece of glaziers' glass. I also utilize real horsehide strops, primarily in repair.
I have no recognized formal training.
(If I worked in front of a 12th century polisher, even though we did not speak the same language, he would simply sort through my supplies and polish a sword.)
Having said that as a back story, I would take your knife and appraise it. I could learn quite a bit by my historical study, a small library, experience and marks on the ricasso. (Polishers removed handles and studied marks and caligraphy.)
Unless you specify a need,
like reprofiling a thicker edge for caping, I would repair and blend out chips, re-form the tip, remove patina (unless it damaged historic value) make the bevel as uniform side to side and front to back as possible, sharpen, and then polish to the most brilliant finish the alloy will hold.
In short, imagine if you took your modern pocketknife, climbed into a time machine set for Edo in 1150 AD, found a polisher and secured his services.
Now imagine holding that pocketknife upon completion.
That's what I would do to your knife...
