Turning a Delica into a Scandi Folder

[me2]

I've seen several members do things like this on old Delica and Endura knives. I have a Delica that is getting very thick at the edge and though this might be a way to get some more life out of it. How did any of you do this fairly drastic modification?

If you mean putting a scandi grind on the Delica, it seems a belt sander would be the sanest way to go. Or you could use the sander to thin out the saber grind and then put on your primary bevel in the normal way once again.

I didn't do a scandi grind, but I did fully convex my Delica. Take a look here (pics of the finished product toward the bottom):

I used a DMT XXC stone to do this. I started with a belt sander, but I think the belts got worn out too quickly on the hardened steel of the blade.

Convexing the thing sounds like a possiblity. I have some unhardened A2 blades I want to grind at 5 deg/side in a convex profile down to the very edge. Maybe I can try the Delica at 10 dps, then 5 if that works.

I used a diamond file and now have a convexed Delica. I mostly did it to thin it, and now I'm planning on giving it a mirror polish.

A belt grinder can do the regrind quite quickly, but it'll be slightly convex. You can get a true Scandi by using a coarse benchstone.

Post pics after you do the mirror polish, please. I did a mirror polish by hand using waterstones on a FFG Delica as a gift for a buddy. It took about 3-4 hours, because the blade was not absolutely flat to begin with. I have not done my own, but may in the future.

I have a saber grind ZDP Delica that I have softened the transition on, and have considered giving a full convex grind some day. Maybe several days. Just rounding where the saber grind meets the full thickness portion of the blade resulted in a significant improvement in slicing ability.

I did this also, I smoothed down the transition and put a mirror finish on the rest. It slices MUCH better than before. Now it glides through cardboard where it used to tear and stick before.

Just today I used a machete to help my neighbors clear some big plants from their yard. Afterwards, I spent some time with the XXC stone on removing the sharp transition between the flat and the primary bevel, prior to resharpening it. Cutting woody stems seems like it would benefit from the same modification that is so helpful on cardboard with a smaller knife. The machete is a basic Ontario, and it is more convexed with each sharpening, and works better every time.

I am still wanting to see pics of the mirror finished Delica (hint, hint).
