Reprofiling vs. regrinding

[norad45]

Can someone advise a knife novice what the difference is between these, if any?

Thanks

reprofiling means to change the angle of the bevel near the edge. Regrinding usually means removing metal to change the shape, thickness or width of a blade.

When I use the term Regrind, it means changing the primary grind, whereas reprofile is just the edge grind. Toa dd to the confusion, adding a relief grind is bettwen the two, not a full regrind, bur thinning way into the primary, then applying an edge grind.

In my mind, grinding a knife is the most basic and, therefore, largest-scale aspect of shaping a blade. Profiling a blade is giving it the exact bevels that it will have. Therefore, regrinding a blade will take off a lot of material from most or all of the blade, perhaps totally changing the bevels of the knife. Reprofiling a knife will enhance or redirect the the bevels, but it won't be as significant of a change to the blade as re-grinding. In a nutshell, I think of reprofiling as finer, more detailed work to enhace existing features, whereas regrinding alters or completely changes the features to form new ones. hope this helps

I have reground many daggers and saber-ground knive to make them hollow ground. More commonly I just reduce an edge bevel down to 10 degrees per side. This reprofiling often produces a bevel that is 3/16-inch wide.
