My Becker-ish BK10 "crewman" in 5160 jeep spring steel.

[hanklet0]

So I use to have a Becker crewman, I lost it after I left it on my bumper of my truck. Not willing to wait for Mr. Becker to make a new one, I made one. I used a leaf spring from my old Jeep springs and used the scales off my BK 7. Its a lil thick, .230. 5.5" blade. I have yet to heat treat it. When I'm done I will post all the various stages of my project. I had a lot of fun.

Looks nice.
I hope they re-edit the crewman !

sweet!

the crewman is the BK-10 btw

Thanks! I keep getting the number system screwed up because of ESEE and there model numbers is relation to size. Can anyone here quickly and simply explain how I can differentially harden the blade?

i'll edit the header to reflect the change :>

the standard method for 5160 is using a tea-pot

or you could probably send the blade out to a customer heat treater for not much $$$?

What is this "tea pot" trick you speak of?

over on the HI Khukri forum, the kamis pour hot water on the parts of the edge and only those parts, they want HARD. differential!

Wow, that is simple. I could even pack some blue clay from the river along the back edge and let it dry before I heated it. This would ensure that no water got on the back edge of the blade. Thanks for the Info, learning just occured.

Great job on that! After the HT let us know how it performs for you.

How hot is the water?

I am completely clueless about the temperatures of heat treatment. The heat required to melt steel is pretty high. I thought the heat treatment temp would be much higher than 120 -200 degree water.

Can someone educate me on this?

the *simple* explanation is that you heat it to a given temp and quench it. the "hot tea water" is for the quench. the steel already has to be very hot, yah?

take a look at this:
http://en.wikipedia.org/wiki/Heat_treatment

that covers the pesky details pretty well in one page. i'm not going to attempt it, leave holes open, and have people hop inside for a free ride on the Bladite express

OK,

That makes more sense. The steel is heated very hot and then quenched with say 180°F water.

Im re-grinding my blade this week. Going to take a little off the bottom of the handle and a inch off the blade to make a 4.5" blade. I want a MAX size in the pocket EDC knife. it will be a one of a kind BEcker inspired blade. I cant wait. Im going to wrap the back side in blue clay thursday night and put it under a heat lamp to speed dry it. "water quench".
