I am just curious how long people spend on a stock removal knife..start to finish. I realize times will vary depending on tools available, materials used, experience and what not. I have been buying blade blanks and making handles/bolster and what not and am thinking I am close to taking the plunge but I feel like I move to quickly thus making mistakes. but with each one I learn something new and get better. Guess I am just trying to see if I am putting the time in needed to be ready to try making my own blades.
 
So far, all I have gound has been my home made chisels for my woodworking.
I'm just beginning the custom knife field, but my woodworking is good.
I just today found a local metals supplier, and asked for a quote on some of the better steels available, so I haven't made a true knife yet (no forge) but I did grind out a new steak knife for my wife out of some really cheap scrap metal I found in an old box in the garage. I have no idea what it was, but in 10 minutes with my bench grinder, I had the shape of a new blade, 20 minutes I had wood handles on it, and another five for grinding and honing an edge.
This was REALLY cheap steel- I could bend it about 60 degrees before I couldn't bend it anymore, blade was about 1/16th" thick.
Not something to be proud of, but everytime it gets dull, I just run it past a stone again & the ol' lady's happy.

When the real stuff comes in, I will be marking my time well so I can find out where I can improve my processes. I'm a process engineer & program manager at my real job. :D
This will be to pay for more toys (tools, rifles, a new Victory Vegas...:D)
 
I depends also I guess the experience... I'm lousy at grinding bevels so I run the belt grinder real slow. It multiplies the time spent but avoids any errors. Now I spend hours to finish my grinding. As I learn the movement and get used to it i'll run it faster and faster, it will reduce the spent time to minutes. But profiling is a fast process, you can cut rough profile in 5 minutes with angle grinder and 5-10 minutes you can finish the profiling in a fast and low grit belt. Most of the time is spent on hand rubbing, It may take hours or days to remove all the scratches and going up to higher grits, depending on the dimensions of the knife. If you make more than one same type of knife at the same time, it reduces the time cost significantly. The steel type does matter even if it is annealed condition, some steels are wear resistant like D2 I use most of the time.

To be honest as a novice I spend for a 8" D2 knife:
Some times 2-3 hours on deciding the shape,
15 minutes on profiling,
1 hour on flattening by hand,
1-2 hours on distal tapering,
1-2 hours on bevels,
10-15 mins on drilling,
5 hours on stress relieving (1/2 hour waiting the kiln go up to 650 C) (2 hours holding at that temp)(2-3 hours slow cooling to 500 C),
2 hours on hardening (1 hour to heat up to 1030 C) (about 1 hour soak and cooling fast)
8 hours on sub zero,
3 hours on tempering,
2 - 3 hours on preparing handle material,
1 hour on shaping handle,
1 hour to 5 hour on finishing touches, file works, polishing etc.
Also add 1 hour on honing and sharpening.

If you make sheath, you should add at least a couple of hours...

In total it takes days to finish a knife, if I forge the D2 stock also we have to add at least 20 hours of annealing. The best thing to reduce the time is to gain experience and to make more knives at the same time. This way you will end up to an average of 8 - 10 hours of work for each knife. For that reason I guess a medium size knife properly put together will cost you more than 80 - 100 $. You add materials and energy, it will cost a knife maker an average 100 $ (including time).

For my first knife the cost was astronomical because of trials and errors, time spent on learning the method, not efficient use of tools etc. For that reason I keep my first knife, it would have cost me thousands on dollars. Now it is reduced to 100 I guess...

Depends on the knife and its finish. I've spent as little as 10 hours on a knife and as much as 100 hours.

Some grinds go faster. Hollow ground blades are quicker to grind for me, but much slower to finish than flat ground. Unsurprisingly, a double edged knife will take at least twice as long - more than twice as long to grind, because I struggle with symmetry and go slow.

A machine finish to 400 grit is much quicker than a hand-rubbed one to 2000 grit.

In almost every case, the most difficult work is also the most valued among knife folk.

But for the unspoken part of your question - without doubt, make your own blades! There is no substitute for that; no pre-made blade can really be your knife. Just my opinion, of course. :)
 
Below is my case when I made my 3.5" fixed blade.

day 1: profile, drill holes in tang, tang tapered
day 2: blade grind
day 3: guard shaped, blade polish
day 4: heat-treat
day 5: polish after heat-treat, handle fitting
day 6: shape handle
day 7: sharpen edge, overall check
 
i have found that on average it takes me approx 20-25 hrs start to finish total time spent working on the knife. I forge so this doesnt take into account annel or normalizing cycles. Latley i have been working with W2 and have spent over 20 hrs just playing with hamon development on 1 knife using various mediums to get different results. It will all depend on what you are working with and what you want your finished product to look like.
 
It takes me an estimate of 4 hours per side to do the bevels with files, It took me about 2 or three hours to set up my filing jig properly, about 20 min profiling, drilling is quick, the next knife I will make I will see how long it takes for me.
