    Beautiful knife, well done! Oh... and... ah... is that background one of the aprons you wear in the shop? :)

    Tempering Oven...Starting Over...

    A PID controller should keep the temp +/- a degree or two. You probably want to add Kawool insulation to improve temperature stabilization. Those countertop ovens are often poorly insulated. To attach the PID I mentioned in your previous post, just rip out the wiring to the timer and...

    Carbide Straightening Hammer

    No doubt beating on a blade will change its shape. But cold working steel after heat treating seems like a bad idea Each hammer blow will set up a stress point in the blade that could lead to eventual cracking or potential further warping. Part of the objective of heat treating is to reduce...

    Sharpening question.

    This is a terrific thread, love the insights and opinions on how we all sharpen blades. Here's my 2 cents: I now only use 2x72 belts to sharpen. Depending on the blade condition, I'll start with 120 on thick edges (if necessary), then 220, 400. 800, (or occasionally 1200 to 2400) then...

    OPauls Knife Picture Thread

    Your craftsmanship is superb, what an eye for style and detail! Did you place a nut on the tang and then attached the antler piece on with a screw, or is it the reverse of that?

    An Experiment To Minimize Hand Sanding

    One thing I've found using this setup for grinding flats on a full grind profile is that a bonded belt running on a hard platen doesn't leave a particularly good finish. The engineered Trizact belt with a some kind of softener makes for a much better surface finish. But, I also found that the...

    Stress relief for 15N20 - will it help with warping issues?

    I just finished 4 AEB-L 7 1/2" hidden tang blades with steel from AKS, no warp problems at all. Plate quenched (hand held, no clamp), clamped in Cryo tank and clamped in tempering oven. I kinda expected a problem, but they came out straight. Also, did not normalize, soaked at 1560...

    An Experiment To Minimize Hand Sanding

    One thing I dislike is hand sanding - on anything. So to preserve my aging hands I'm always looking for a way for a machine to do the work. I've begun making more kitchen knives and I've fiddled around with some grinder attachments that seem to offer a way to get a hand sanded look in rather...

    Hey wait a minute - I NEVER EVER said that any of my tools are more important than my Lund bass boat. We gotta keep things in perspective, there are indeed a few things in life more important than shop tools...just a few. :)

    any good design ideas for push knives?

    Here's an idea for you, fix'in to plasma cut a push knife from a saw blade. After the cut. I found that having both "wings" was kinda awkward, so I whacked off one of them. Showing a pretty crappy handle fit-up. The shape of the handle fits comfortably into the palm. The full half circle...

    Documenting Heat Treatment With Paragon's Bartlett Sentinel Controller

    For the past many years I've said the exact same thing, word for word. But several things changed my mind: - It seems to me that making knives is fundamentally all about getting the metallurgy right, everything else is "mostly" window dressing - in my very humble opinion. - I learned in the...

    Documenting Heat Treatment With Paragon's Bartlett Sentinel Controller

    The HT data is downloaded in a universal CVS file extension format. Excel automatically imports it. But, you will want to save it in an XLSX Excel spreadsheet file format extension to gain full use of Excel's features. I'm PM you with some details about how to create a graph from the HT data.

    Old dog. New trick.

    That's exactly why I don't like to hand sand - I've gotta try this.

    Documenting Heat Treatment With Paragon's Bartlett Sentinel Controller

    The WiFi connection is pretty easy once you dig into the controller steps. I'll give it a shot here: - 1st set up your WiFi connection using the WiFi icon on the main screen and check to see if you have Ver 4.83. If not call Paragon and get them to download it to you. I'll PM the name and...
