To me, the term "custom knife" means that someone provides a knife maker with the specifications, and maybe the design or idea of a design, and said knife maker makes the knife to those specs &^ designs. It might be a radical design or it might be "CUSTOMER SPECIFIED" changes to a stock knife.
I don't make custom knives. I could, but I just don't want to put up with the hassle of pleasing picky people. So, I just make knives in my spare time. Hopefully, some people like what I design and make, allowing me to loose less money.
I started making knives with a band saw, an angle grinder and some files. Each blade blank produced took a while.
Now, I use a water jet to cut my blanks, whether I'm cutting a single blade or a batch of 30 or more. As an example of WHY I believe one should consider using a water jet - I recently cut out 30 13" blade blanks in about 85 minutes, 57 of the minutes being the actually cutting time. I had already designed it, drawn it up in Autocad and converted the Autocad drawing to the water jet control file previously for a previous cutting session (about 5 hours of work from start to finish). All I had to do this time was boot up the control PC, load my file, calibrate the water jet and my steel blank, push "Start" and watch.
What was my cost? $114 - I paid $2 a minute to use the waterjet and it took less than 2 minutes per blank.
Had I used a band saw to cut them out (as in the "good old days), I would have had to paint each billet with layout dye, let it dry, line up my template and trace out each blank. THEN I would have had to cut each blank individually, with my fingers within inches (or less) of a high speed blade. About 2 minutes per blade for the prep work, and then probably about 30 minutes to cut each EACH BLANK, as I go very slowly. I have 10 intact fingers and would prefer to keep them that way. I probably would have had to change out the band saw blade at least 1x.
I realize some folks don't think using a waterjet is "kosher" for custom knife making. IF I were to start making custom knives, I would STILL USE a water jet. If I were to take the customer's specs/ideas, design the knife blank profile on paper, transfer it into a CAD program, convert the CAD file to a flowjet file, cut out the blank, do the prep grinding, and do the finish work, after sending it out for heat treating, I would claim that the knife I produced was a custom knife, even though I didn't do 100% of the work (didn't do the HT).
I prefer to have my HTing done by PROFESSIONALS who know metallurgy. I could study up on the whys and wherefores of properly heat-treating steel to become a metallurgical guru, spend $KKKs on equipment, spend a lot of time HTing each blade, etc.... OR, instead, I can drop off my HT ready blanks, tell them the steel type and what target RC I want, go off and do other things that are both more fun and more profitable. When I get the call that they are ready about a week later, I go back and pick my HTed blades.
I'm happy to be a 99%er.
