I have been making knives for about five (5) years now. I am still stuck in beginner class! I'm not sure that you ever pass that class and get to leave.
When I first started making knives. I made them all one of a kind. One at a time. One design, one knife. It took a long time for me to make that one knife.
After I made a few knives, I started making the same knife design and attempted to finish them differently. Perhaps, one with a wood handle and one with a bone handle. Or one with a front bolster and one without a bolster. This method made it much faster to make several knives. Obviously you get a similar knife. Not an exact knife - if there is such a thing.
At one point, I made 17 similar knives for my nieces and nephews. Same knife design, they picked the scales. Some had bolsters. Some had liners, Most chose G-10 in a variety of color combinations. It took me about a year to finish all of them and the sheaths. I would still be trying to finish up if I made them all a one-off.
Looking at your pair, I just had to ask if that was your thought process. Making two similar knives is way faster than making two one-offs.
Good thinking.
Keep grinding.
