I find that Nick's captions are WAAAAY better when he's got a good night's sleep in him.
Enjoy.

Well, even after all of the stuff I did to ensure everything would fit together just right--- I THOUGHT I saw a gap on the top side of the handle when I took the knife out of the glue-up fixture. Since that would mean scrapping this handle, I ground everything down at that spot just to check. WHEWE... it was just some kind of optical illusion as everything fits just like it's supposed to;
We need to drill a pin hole. One thing I screwed up a lot when I was first doing this kind of knife, was getting the pin off-center in the handle. After awhile, you can eyeball it pretty easily, but it doesn't hurt to have a reference. I start by putting a straight edge over the handle that runs up, in-line with the spine of the blade. Then do the same thing on the choil side;
I do just eyeball the overall location of the pin, but one of these Center Rules is very handy for helping out with centering the pin. Side-note, I have a world class Mastersmith friend that DESPISES pins because it disrupts the flow of the knife to his eye. And it's kind of funny because we both seem to like similar type of knives, yet I LIKE a pin not only as a mechanical fastener, but because it's kind of like "dotting the i" or "crossing the t" for me, it just looks right to my eye

Here's a drilling fixture I use. I made this back when I was making tapered full tang, stock removal blades and realized you can't lay a tapered blade down on the dill press and expect the holes to still be perpendicular with the table. That idea transfers well for drilling a hidden tang as well, since the ricasso is FLAT and PARALLEL, I KNOW that if I clamp the blade down by the ricasso then I can drill through the block/tang and have the hole be absolutely perpendicular to the ricasso;
You don't want the handle to flex downward as you're drilling, so there's this little adjustable support to ensure it doesn't;
Here's everything set-up for drilling;
Close-up of the same. Now here's the thing here--- When you drill down through the block, and hit the steel tang, it's going to make the bit want to wander before it grabs and penetrates the tang. If you're not careful, you can REALLY warble out the hole in the wood block this way. There are a couple things we can do to fight this. 1.) Start with a bit that's a little smaller than our desired pin diameter. (I want to use a 3/32" pin- so this first bit is 5/64") 2.) Make sure the knife is SECURE so the drill or mill can't move it around. 3.) Use basic machining figures for your feeds and speeds (that means this little bit needs to be turning at a blazing fast speed- and you bring the bit down in light "pecks";
When it comes time to get the hole up to the correct size, my PREFERRED technique is to use a CHUCKING REAMER. A reamer is the standard go-to tool for making a drilled hole round, clean, true, and precise. Unfortunately, my shop secretary neglected to order me some new reamers!!! *eek*

So I'm going to do this with a drill bit. I'm using a brand new, cobalt 3/32" jobber drill. I haven't moved the table/vise AT ALL, so I know the spindle is still perfectly in line with the hole. I don't want to contaminate the hole with cutting fluid (it can seep into the wood) so I use my trusty wax again. This time, I'm using the fine feed for taking the spindle down, and do it in one smooth, continuous motion.
The reason for all of this semi-technical hoopla for a silly little hole, is we don't want to go through all that other work only to end up with a pin that has a "halo" around it because the pin hole is too big for the pin.
I'm sure there are hundreds of makers that just lay the handle down on a drill press, force an old dull bit through the handle and tang, and get a perfect fit for their pin--- but experience (many times over mind you) proves that I am not one of those guys!!!

The next three images are an almost overly simple explanation of what I'm going to shoot for with the handle shaping. This is a little more for my friends and family that are looking at the pictures on my Facebook page--- as I'm sure most all makers and collectors on BF already are more than familiar with these ideas. First up, this is what I like (not everyone I'm sure, but hey---this one has my name on it!)

LOL;
Here are some things that I do NOT want. Note the abrupt "ledge" on the top side of the handle, as well as the hump (this is very common with newer makers when they don't get the correct angle on the front of the block--- yes, I mean ME

). Also the guard is NOT thinned down... this is a double negative- for 1.) It looks clunky and 2.) It leaves unnecessary weight in the handle (the guard is steel, you're not going to bend it with your finger). Another thing is that very thin bit of wood right at the finger guard. I don't like that as it's leaving a vulnerable little piece of wood that doesn't need to be there (IMHO)
Overall, the handle is too wide for the blade... but if I had to choose too wide (like this) versus too narrow (next image) I'd choose too wide. Of course we are shaping the handle as we choose--- so we will choose to do it right
