Yes. He's got a deal with Kyocera, and has for ages. He also has some of the best knife technique ever. That guy can flat prep.
MAC Original, Superior and Chef, Kanetsugu, and any Sabatier can all be effectively sharpened on oil stones (as opposed to water stones). Oil stones are less expensive and far easier to maintain than waterstones. So, I think they're best for the direction you're heading in.
You're going to need to reprofile the Sabatier -- assuming it can be saved. Knives which have gone through the diswhasher frequently have such major handle issues it's not worth repairing their blades. That means having a coarse enough stone to handle that task -- but it's a surface you won't use very often. So, I hate to spend a lot on it, or waste a lot of space. The alternative is to have something just coarse enough to profile, but fine enough to use as the first sharpening surface. The equivalent of a fine Crystolon or medium India if you know Norton stones.
That you're even discussing freehand sharpening on stones indicates an interest in a well finished edge -- so you're going to want your final surface to do more polishing than sharpening. Assuming, these are good guesses, here are two recommendations.
Hall's Commercial 8" Wet Hone ($48 -- three surfaces)
Commercial Knife Sharpening Stones Commercial Knife Sharpening I recommend the Commercial over the less expensive Home Tri-Hone because the Commercial stone holder can go into the dishwasher, stones and all. More about specific maintenance issues if and when you decide to use oil stones. Suffice it to say, they do need to be cleaned frequently, but don't need to be prepped ever, and only very infrequently flattened. The Norton equivalent has a better rough stone, a better box, not nearly as good a soft Arkansas, and costs double.
Four surface, mixed set: Norton 8 x 3 x 1 coarse India; Norton 8 x 3 x 1 fine India; Hall's 8 x 3 x 1 soft Arkansas; Hall's 8 x 3 x 1 black Arkansas. This is the set I use for almost everything (about $150).
Here's a different way to go...
Four surface, Japanese set: Norton 220/1000 and 4000/8000 combi water stones. The set comes with a flattener. You'll need to add a stone holder and a nagura prep stone. (about $150, altogether). Not the best waterstones in the world, but not the worst. More polish than you need, but you can't beat the price with a good 220/ 1000/ 4000 set plus flattener -- so you might as well start here if you decide to go the waterstone route.
Most professional sharpeners will "fix" a broken tip by reprofiling the knife completely. If you're good enough to recreate the old profile, you're also good enough to know it's not worth what the customer will have to pay for your time. It's not a cheap repair, and it's important for the customer to have a very definite idea of what (s)he wants so as not to overspend. If you have somebody else do it, make sure they take off enough to form an entirely new point rather than savying the old, and tell them you don't care about retaining the old blade's shape.
If you do it yourself, the best way to take care of a broken or highly deformed tip is to create an entirely new point without trying to mimic the old geometry. And usually the best way to do that is by sharpening down from the spine, rather than up from the edge.
First create the point, by holding the spine square to the stone and slowly abrading a new tip. The farther back towards the handle the more like a "spear" and regular French profile the knife will look. The farther away, the more like a sheep's foot or santoku. There's a common Japanese profile that splits the difference -- which is what you'll probably end up with. Start grinding about 3/4 to 4/5 of the way to where the tip is going to have to be and don't worry too much about curving. Start gradually, then increase the degree of arc as you near the point (by lifting the handle).
Once you've established a point that meets healthy edge, you can start profiling it -- still from the spine until it's got a shape you like. Take your time, it's a lot of work and you won't want to go back. Then, take care of an outstanding issue you didn't even know you had. That is, round over the spine in the inch or so closest to the hande. This will make the knife a lot more comfortable to handle.
Finally, profile sharpen and polish the edge. Whatever's still left of the edge is not only dull, but probably pitted from dishwasher detergent, and wildly inappropriate for someone who can sharpen her or his own knife. If the old Sab is a carbon, I recommend a flat bevel, with 50/50 symmetry and a 15 deg edge angle (30 deg included angle). That's how I usually sharpen mine, anyway. If it's stainless, we'll take it out at about a 20 deg edge angle.
If and when you get there, I'll give you some very specific instructions for how to do the point and edge profiling, and the edge sharpening and polishing. Not to mention how to hold the proper angle consistently, and how to use and take care of your stones. Right now, I'm just trying to let you know you can do a good job of it.
