(I’m not putting this in the “CBM” thread because it’s not done yet, and because although for the most part it worked great in one respect I want to share it as a cautionary tale, and also this is filled with long-winded musings).

So my ideal EDC would have a few main characteristics:

1 3.5” blade of decent steel
2 Wide & flat-ground for slicing
3 Pointy but strong tip
4 blade somewhat thick, over 1/8” but probably not over 3/16”
5 Tip at or below midline, as opposed to a big-belly/skinning profile
6 Axis or button-lock so no danger of cutting oneself when closing the blade
7 Full liners for strength
8 Good blade-to-handle ratio
9 comfortable in multiple grips
10 non-metallic scales (I love titanium handles, but not when very hot or cold)
11 a flipper or choil that prevents the index finger from getting cut if the lock fails and the blade closes
12 a solid hand-filling handle
13 but not super-bulky in the pocket
14 a wave, or wave-able
15 balances at index finger

When you write them out that’s a lot! Anyway, I have never found a knife that met all of these. The BM Ares came close buy didn’t feel quite right in my hand. Then I saw the HK, read the good reviews, and thought “let’s try it.” So I ordered one online. When it arrived I was very pleased with it . . . except it was a bit short for my hand. That was also why I had to sell my ZT 801, a great knife that met most but not all of my criteria above.

Can’t lengthen a handle though . . . but unlike the ZT, with the HK I realized there was room in the index choil to remove some of the steel in the liners near the blade tang, making more finger-room on the handle! Dare I try? I have ruined many a cheaper knife experimenting on various mods . . . but a few have succeeded, so let’s throw caution to the wind, or more accurately my HK to the belt-grinder.

I did it and the result is fantastic! It is SO much more comfortable in hand for me, and I think it looks better now too *except for the grungy scales at choil - see below), and it now meets criteria 9 as well as 1-8, 10, 13 and 15 above. Once I make slightly thicker handle scales it will meet #12 as well. I attached one “before” and a couple “after” pics. Some modifications were functional, some were esthetic, and some were both:
- Carve away liners/scales to allow index finger closer to blade
- Reshape index cutout and blend it to continue “coffin” flow throughout handle
- Reduce width of guard
- Slightly change lines of top of handle to be more angular & match overall design
- Slightly reduce/contour the jimping hump above the axis lock, so it flows with the design a bit more w/o reducing strength
- change out clip to one that didn’t annoy my hand as much (modified a Kershaw clip; need to darken it somehow)
- slightly widen the bevel around the axis lock for better access
- polish the scales at the edges but keep texture in the middle
- file jimping notches into the scales to match the liners
- sand the edges of the liners so that all the stainless steel is exposed on the edges
- put a swedge on the blade, and slightly grind it to more of a drop-point (the tip is still strong but now it is POINTY)

Now for the cautionary part: I was careful when reshaping the liners not to remove too much and expose the blade tang. BUT in contouring the scales by the index finger cutout, to give easier access to the thumbstuds, I did not realize that the scales are hollowed out for the axis springs. Duh. So I sanded right into the hollows, exposing them from the outside. I was able to fix that with some black-dyed epoxy, but It doesn’t look or feel perfect. Since I will be replacing the scales anyway I will fix that, but it’s a bit tricky because there is very little thickness between the hollow and the end of the modified scale. I may have to do aluminum bolsters just to have enough structural integrity there.

Once finally done I will post it in CBM. Hopefully next weekend, hopefully! The big challenge will be figuring out how to center the holes in the scales for drilling - the holes in the liners are D shaped not round, so it’s hard to use the liners as a template. Anyone have any ideas for that?

No one has ideas on how to center holes in new scales?

Center what holes?
Scales screw holes? Pivot hole? liner holes?
Excuse me if you have already stated which holes you are talking about.
But, I can't seem to figure that out.
 
Sorry - I meant that the holes in the liners for the pivot and standoffs are d-shaped rather than round, to prevent rotation. This is a nice feature but makes it hard to use the liners as template for drilling those holes in new scale material. I guess I can use the existing scales as a template but I am worried that won't be as precise.
 
I would use the scale.
I mark the pivot hole placement first.
I find a drill bit the same size as the hole I want to mark.
I then hand turn the drill bit in the hole, this marks the center of the hole.
I then drill a pilot hole, counter-bore & through hole.
The next hole I do is the one that is located the furthest away from the pivot.
I mark this one in the same manner, but this time I have the addition of the pivot in it's hole ....anchoring the other end of the scale down.
Then I drill the pilot hole, counter-bore & through hole.
I then anchor the entire scale down with these two completed holes.

Now at this point you have two choices:
If you want super accurate continue this same process, one hole at a time, until you have all of your holes completed.
Or
You can mark the remaining holes, then drill the pilot holes, counter-bores & through holes for all the remaining holes all at same time.
