    Stop Tru-Oil Hardening

    In an earlier posting, most of us complained about Tru-Oil hardening in its original container. Here's one way to keep it liquid. I simply transferred to the oil to syringes which minimized the amount of air exposed to the oil. I made a little cap plug from some moldable plastic and made a...

    Milling the Primary Angle?

    In Don Robinson's book, Slipjoints My Way, he demonstrates cutting a blade's primary angle on his mill using a tilt table. I would show a photo, but don't want to violate his copyright. Don actually mills two blades using this method, connected end to end on one piece of metal. It's a clever...

    Using the Viel Grinder to make serrations - Proof of Concept

    This is a follow-on posting to my earlier post where I questioned whether a Viel Grinder could / would make satisfactory serration grinds before I bought one. Well, after some brief testing, I think the verdict is in - it works! With literally no modifications, this grinder will place...

    Grind Serrations with a Profile Grinder? What'da Ya Think?

    Just saw this grinder on CL and thought it might be adaptable to making accurate serration cuts on a blade edge. Has anyone tried using this kind of grinder for that purpose? It's primarily used for making customized molding cutters for wood working.

    Warped 26C3 Blade - A Little Fixing Tool

    With my first venture into thin 26C3 (.78") I found an ugly 1/32" lengthwise bend/warp after HT in Parks 50. After tempering at 350 the steel is around RC 64ish, per AKS graph. The warp would not move with cold bending. I read that placing the blade back in the oven and coming up to the...

    A Little Known Craigslist Search Method

    Most of us have used Craigslist with varying degrees of success. A few months ago I ran across a phone App called Cubix, an App that let's you monitor or "crawl" across whatever Craigslist location you want to view. You can customize the settings for location (all US, state, city), subject...

    Parks #50 Sourcing

    I need some fast oil for some 26C3 knives I'm making. Common knife making supply sources are out of the stuff. Based on KD postings from McCaffery & Cashen, etc., I decided to only buy the original certified Parks #50. I called Maxim Oil, 817-293-4645, they sell the original Parks oil...

    Need Advice - Hidden Pins on full tang

    I'm working on a kitchen knife and have selected a piece of beautiful Birdseye Maple for the scales. This piece of wood has great eyes coupled with brown tone marbling. I started to consider using traditional full through-tang pins. But, I'd like to not take away from the beauty of the maple...

    Today I Fell In Love With A Polymorph

    Actually Polymorph Plastic - Sorry for the cheesy click bait subject line, couldn't resist. Here's the story. Long ago I purchased a Japanese cleaver and over the years it has suffered from heavy use and eventually a broken handle. To repair this I want to make a WA Style handle with a solid...

    Needed a longer tumbler - so I made one

    I've been using "Tumblers Tumbler" for stone washing small knives, but it's too short for larger knives. So, I decided to use the 2x72 grinder to roll a 4" PVC pipe. A design concept similar to others I've seen on the InterWeb. I set the pipe so it just touches the 2" contact wheel, using a...

    Dust Collecter / Air Filter - A Design For My Shop

    For a long time I've been frustrated with dust collection and general shop air filtration. I've used the common box Delta filter that often hangs from a ceiling with limited success. A fixed shop evacuation system with ducting doesn't work for me, much of my equipment is on wheels and too...

    Made Some Small Rubber Contact Wheels

    Small rubber contact wheels are hard to find, and when you do, they seem expensive. So, I rooted around in Amazon and found a rubber sanding drum sleeve set in 3/4,1,11/2 and 2" diameter x 4.5" long, and then found the needed end bearings. The rubber tires cost $19 and a set of 10 bearings was...

    Makers Mark / Logo - On The Left or Right?

    Here's one of the those dumb questions from a newby knife maker... Am I right that most knife makers place their primary Mark or Name on the left side of the blade? I've been placing my name on the left side because that's what I see other do with their knives. But, why isn't it more...

    WARNING - Potential 3M Filter Fraud Alert -UPDATE

    A few days ago I purchased 3M 2097 pancake filters on Amazon. What I received was filters were labeled "3M 2097 CN". I knew from previous purchases of N95 mask type face filters that if filters have a KN suffix (N95 KN) that those filters were made for use in China, but sold here in the US...

    Quench Oil Preheat Questions

    I'm about to change my quench oil from using only Canola to both Parks 50 and Parks AAA depending on which steel I'm using. I understand from USAKnifemaker website that Parks AAA works best with oil pre-heated to around 120°F. I also read that Parks 50 should not be allowed to exceed 120°F"...
