I"m just wondering if any of you use a flat stone or diamond flat to sharpen your Spidies?
I don't currently own any spydies but I'll speak up anyways. Either a sharpmaker or a plain stone will work perfectly provided you know what you're doing.
I do own a sharpmaker and I find it to be a very useful tool. Depending on which knife I'm sharpening and what my mood is I either sharpen my knives with the sharpmaker properly set up or I just use one of the sharpmaker's stones freehand.
It's easier for me to sharpen with the sharpmaker if:
-The knife has a very small edge bevel
-The blade has a downwards curve (such as a hawkbill)
-I'm in a hurry
-The edge/bevels are not ground evenly/properly
-The edge has serrations
I prefer to sharpen freehand if:
-The blade has a dramatic curve (such as the front part of a spey blade)
-The blade has an edge bevel of neither 30 or 40 degrees
-I want to use a lighter touch
-The blade has a wide edge bevel (such as my chef's knife)
-The blade is longer than a few inches
-I'll be sharpening the knife while watching a movie or something like that
