@dspacioI previously posted above, but here's an update:
When I got the Myerchin, the overall quality looks good.
It was not quite as "grip friendly" as I had hoped.
However, I am extremely particular.
The back of the spine is ground flat, perpendicular to the overall blade. This makes a very sharp 90° edge along the spine.
I wanted a smoother surface for the base of my fore-finger to rest on when doing "fine cutting".
I used a very fine "Swiss pattern file" and several strips of "emery" cloth to "soften the edge".
(The spines on all my kitchen knives have been softened: German, Japan, Swiss, Chinese, etc.)
Both ends of the handle had slight "points" which I also softened.
The blade looks good, but I was surprised to find the tips of the 3/4 serrated portion are "round", not sharp points. (maybe .025 mm radius)
The front 1/4 blade portion is quite sharp, with a medium surface.
I will try it, but will probably use a coarser stone to re-sharpen.
I am not a fan of belt attachment clips; seems too easy to fall off.
It can easily be removed w/ 3 tiny screws.
The handle attachment ring is small.
I installed a 3/4" split ring, which will easily accommodate a carabineer.
Just an update on my Myerchin:
I stated above:
"The handle attachment ring is small.
I installed a 3/4" split ring, which will easily accommodate a carabineer."
After using this split ring for a relatively short time, w/ a carabineer, the knife's attachment ring sprung open & the knife fell away from me. This attachment was not as sturdy as I had assumed.
(I assume the carabineer twisted the attachment ring, which just "clips" to the handle by spring pressure.)
I found the knife, but not the attachment ring. Myerchin sent me a new knife attachment ring.
I had it TIG welded to the handle.
Note: The ring has a sweet spot of orientation, to allow the Marlin Spike to be locked, so adjust before welding.
