Help me with knife harpenining?

so i got a sharpmaker and a swiss army knife OHT as my knife. i reground it and got burrs on both sides but can not get a sharp edge. what am i doing wrong? not removing the burr?

The sharpmaker has a 40 degree and a 30 degree setup. Victorinox says to keep a 15-20 degree angle when sharpening, so I'd go with the 30.

Neither of the stones are particularly aggressive, so if in regrinding it you change the angle, you may want to start with a heavier grit stone. In my experience, the sharpmaker is really just for touching up dulled tools while my heavier grit stones are for restoring them.

the burr must be removed for sharpness. Bevel angle and polish are secondary to having two flat planes terminate cleanly. You can either use finer stones to work the burr off leaving a high polish edge, or strop it to break it off leaving a rougher but still very sharp edge

Its worth specifying 30 degrees INCLUSIVE, meaning 15 degrees from center for each edge (so as to not confuse the new guy), which is a nice slicer.

Swiss Army knives use a nice soft steel, theyre almost impossible to not get sharp.
Try slicing some paper, if it bites and tears the paper you got a toothy edge and some burs. In other steels this could be points of uneven carbides but being that the Victorinox has almost none to speak of its almost certainly a burr.
If it slices, but just not really well then your angle is probably too wide and the blade is too thick behind the edge.

As far as "regrinding" you wont be doing any regrinding or re profiling with a sharp maker. Just make sure you're letting the stones do the work and you focus on even strokes at the right angle.

The one time i tried to sharpen a really soft blade, the bur was more like the entire edge rolling over, which is what I suspect might be happening here. Solution was to go from 30 degrees inclusive to 40. Was using a sharpmaker on the original Cold Steel Spike. Neat design, crap steel.
