Finished up my second slipjoint last night. I'm excited to have a knife I can be proud to carry, instead of my first attempt, which was an abomination of a knife.

Specs:
Steel: 3/32" A2 @ 61 Rc
Heat Treat by Peter's
Covers: Brown Canvas Micarta
Pins/Liners/Bolsters: Nickel Silver
OAL Open: 6.4"
OAL Closed: 3.5"
Bolster to Tip: 2.8"
Plunge to Tip: 2.4"
Thickness: .40"
Hand rubbed 320 grit finishing the blade, 800 inside the liners and buffed on the covers. I need to go back over the handle again though, it looks like.
The edge is .0015" right above the sharpened bevel. I ran it about ten strokes on each side on a very old 400-600 grit silicon carbide stone, then stropped. Very easy to sharpen with that thin edge, even though with its high Rc.

All numbers are rounded to the tenth, that's why they don't quite add up exactly.

I am pretty upset, I think I grabbed a piece of stainless rod for the pins instead of nickel silver. You can see the pivot looks like a different metal entirely. Live and learn. I'll make sure I never do that again!

Bear with me, there's going to be a bunch of pictures. I couldn't get my makeshift photo booth to work, so like McDonalds, you get a bunch of mediocre instead of a little great. :)

The scuff marks are where I messed up and laid it too flat on the very first stroke sharpening it, not leftover grinding marks. I am not going back and fixing it, because its going to get a lot more dinged up before this is all over. I would never send one out like that though.

Wow, this look horrible close up. The covers look like poop, and the nick is horrible. I'm buying a dovetail cutter for my next one.

Now, what good is a knife if it can't cut? No good I tell you! So.....lets cut! It was late last night, so I grabbed some leather scraps. This is roughly 8/9 oz. leather, about 1/8" or 3mm for our metric friends. I actually did all the cutting before I took the rest of the pictures.

What I began with:

It shaved hair easily before the test.

Cut 126 pieces of leather.

Shaved afterwards.

I wanted to get a video, but I didn't have a videographer to take it. The cuts weren't sawing, they were easy, clean slice, slice, slice, slice over and over. I was very happy with the laser like cutting of this blade, especially given the very marginal sharpening I did. I'm going to take the edge up to 1000 or even 4000 today and see how amazing this edge can get. Very happy with Peter's Heat Treating.

Critiques, comments, criticisms welcome and encouraged. Tear it apart, I want the next one to be better. I already have a long list I want to fix on number 3.

I am posting this in Traditionals, Shoptalk, and [gulp] Customs due to the wide variance in types of people who frequent each forum. I'd like to hear everyone's feedback to become better. If the Mods take issue, I will respectfully redact my posts.
 
Aah in the beginning! What I like about the knife is it has all the earmarks of
someone just starting to make slippies. Way cool. I'm sure there's a million things
you're chomping at the bit to fix on your next one. Find some way to do mill reliefs.
The addiction will grow. Very cool to carry one in you're pocket.
Ken.
 
Ken, what are those earmarks, because I already hate ththene sound of them. Lets get them fixed. You arent going to hurt my feelings.
 
That is one helluva first attempt. I won't even attempt to point out imperfections, I will leave that for the master knife makers. I really don't have any room to talk until I have made a few of my own knives.
 
Way Cool..I think it's great. I have made one complete knife, and several re-handles. My plan is to really gear up this Fall, time permitting. Like my avatar says.....still in training mode.
 
Very good.
I personally think the blade is disproportional to the handle, but if made to a known pattern, must be right.
Seems as though you know what you need to improve on.
Practice makes perfect.

Yeah, it's made to a pattern sent to me by Tony Bose. In what way do you think it's disproportionate? Some of my pictures make the blade look too short, some make it look too long. In hand it feels just right. Sometimes I think GECs blades are way too long for their handles, but then again, I've never handled one either. I am going to go outside and cut on some wood today and see how it feels.

To me, blade looks too short and too small in profile, spine to edge. But you've explained T. Bose sent you the pattern.
 
Well......the length is dead on wrt the pattern. I lost about 1/16 in spine to edge due to a dumb move with my hand while grinding. So, yes, it is a bit narrow. Good eye. :)
 
MEDIC...I think thats an awesome second attempt..Yea its got a few? flaws but ive had factory knives worse than that (yeah cheap ones)..You got the blade nicely centered which is an effort itself...Well done!!...I must ask though..Do you use an old BROWNIE to take your pics? They just about look sepia!!...................FES
 
I like it. Great work. The fit and finish looks very good and I particularly like the micarta scales. Looking forward to seeing more.
 
Well here goes I didn't want to necesarilly point out a bunch of stuff but---- the blade to me
too is a bit off-- needs some belly. Looks like you cut thru the spine I could be wrong but if you
did, that type of full length swedge covers it. Even a dremel will work to relieve the tang area
so it does'nt scratch. We need a choil so we have a place to begin sharpening from. And we
need to go to pin peening school.
Again I'm not in any way taking away from your build its great, and way better than my first ones.
The thing with slippies is this stuff does'nt come over nite and every milestone is a victory. At
the beginning you are up against all manner of problems, be patient.
Ken.
 
Wow! For your second knife, this is really impressive. Keep at it, and I'm sure we will see a lot of good things to come.

Are you self taught, or are you learning/apprenticing from a master/accomplished knife maker?
 
Here's a quick pic of where I was 10-13 years ago. I'm not in any way ashamed to post
a pic cause I was taught by myself. I could'nt turn a computer on let alone search for any
wee bit of info that may have been on it. Learning curves today are totally new, all I had
was a desire. So when I'm trying to help its in no way putting your work down. Again be
patient. With todays info you can probably do it in a fraction of the time.
Ken.

Now, that is what I'm talking about!! I need that to get better!

My tooling is a Craftsman 2x42 grinder and a HF 5 speed table top drill press. I upgraded the platen to a ceramic tile, but it still is HORRIBLE. I'm head to town right now to find a piece of 2x3 angle and I'm going to order a piece of glass from Tracy to make a better platen. That will hopefully help my grinds a bit. I did in fact blow through the spine on the back. I was using my carbide faced file guide for the first time and it hit the side of my platen mount and I totally blew through the spine while I was trying to figure out what happened. Really made me mad, so I did the full length swedge, which I'm not impressed with at all. Also, I ground the edge too thin and lost about a 1/16 or a little more from the edge, which of course took all the belly out.

I burnt up my dremel, but they come up used all the time, I'll find one to use for liner relief.

Frankly, my pin peening is horrible. I have absolutely no idea what I'm doing, or barely any idea anyway. I need help with that. I used the tapered reamer on the micarta, which I think was a mistake. It made the holes too big at the top. Also I had too much pin sticking out from one side when I started peening. Another big mistake. I though I could fill the too big holes by using too much pin stock. One mistake compounding another.

Can you help me with my peening?
 
Others may do it a myriad of different ways, this works for me. By hand, if you
look at the hole of the side set at an angle that little chamfer is all it takes. About
.050 of pin sticking out either side of the bolster. Make sure to have your shim
stock in place and peen with the blade in half stop position. Supergrit, carbide.
I believe it was a #14 bit in supergrits lineup. Ken.

Well........you see.....it's like this. I tried to make a light box, but the outside lights were, among others, the pendant lights above our kitchen island. They are a bit yellow, very yellow apparently. Lol. I really need to spend $20 and a couple hours and make a decent light box.
