Keeping Global knives razor-sharp?
Any hints/tips/advice? Thanks....
The best advice on sharpening I ever got was from a knifemaker whose motto was "The best way to have a really sharp knife is to never let it get dull". In other words, whatever your favorite means and tools for sharpening and honing might be, it's better, safer (sharp knives are actually safer than dull ones) and easier, once you get in the habit, to touch up your blades frequently than to let them ever get to the point where they need a major sharpening effort.
For Japanese steel, I suppose that the traditional tools would be Japanese water stones, but in the end, it's a matter or whatever tool works best for you - one that you are comfortable using and one that you can learn to master.
The only other advice I would give is that *in general* it's worth learning how to manually sharpen. While it is possible to do a good job on some types of steel and blade shapes with some of the automated/motorized tools that are on the market, I've seen far too many knives whose working lifespan has been seriously reduced by overly aggressive removal of metal by mis-use of automated sharpeners of various sorts.
If you've spent the money to buy a good knife, spend the money and time to learn how to care for it and use it, and you'll likely be able to pass it on to your children or grandchildren.

Warthog gives excellent advice. I recommend Shapton water stones, DMT diamond bench stones, and for a quick touch up, the Spyderco Sharpmaker.
It's true that wetstones probably give the best result. It's also true that if you don't know what you're doing, you can end up making matters worse.
After several knife sharpening gadets owned over the years, I finally have one that I'm satisifed with.
Looks a bit ungainly (and mine doesn't have the bright orange handle in the amazon picture), but it does /seem/ to do the job better than others that I've tried in the past.
Of course, your wetstone technique may be much less inept than mine :-)
As always, it depends on what you consider razor sharp.
Global factory edge is about 15 degrees, with a convex grind. See the sixth paragragh down in the link below from the Yoshikin website. If you want to replicate the factory edge, you need a method that can give you a 15 degree convex edge. But you can still get them sharper with smaller angles, which is what I do with most of my knives, including Globals. However, I grind flat edges, rather than convex.
One of the advantages of hand-sharpening with stones is that you can customize your edges, including sharpening each side with different angles.
