Well today I finally got the courage to clean out my garage and restore my work bench to its former glory. After that was finished I went on to finish my second forged knife. When I started it I was inspired by matt's letter openers and a video I saw on YouTube. So with my basic plan I went out snatched a railroad spike and began my work. In all honesty I didn’t think it would work and I would end up scraping the whole project (lack of process pics) but everything seems as if it turned out ok. The only thing I’m concerned about is that this blade can’t hold an edge very well. I’m not sure if it’s just because of type of steel I used or how it was quenched. Starting off I hammered out the narrow handle and then the blade. Then I heated it up as hot as I could get it and then stuck it in the vice and did a 90 degree twist that would separate the handle from the blade. After a quick polish (just getting the black stuff off) checked things out then heated it back up and quenched. I was even able to put a bevel on the spine of the blade like on a katana don’t know what it’s called though... I didn’t do the best job on the actual polish but I think it looks ok. Then I wrapped the handle in leather to make it seem a little bigger than it actually is. what ya think?

Yeah that looks like a knife. Did it banana up on you (curve back), and you ground that bit off? You mention quenching it, did you then temper it?
Motocross goggles are the best workshop goggles hey.

DS, great job! you either got it too hot or not hot enough then quenched it, or your RR spikes are just not the good ones.

it was one of the ones that had HC on the head. and yea brenno it did curve on me i tried to straiten it while it was hot but thought it would be best to just grind it down. i didnt temper it because i didnt want to soften the metal up any more than it already is.

Don't worry about the edge holding ability. Railroad spike steel is never going to be perfect in that respect. At best expect a tough knife. Not a sharp one.
I am impressed. A good effort. Your forging has come on in leaps and bounds.
I like the fact that you have gone for a twist. A twisting wrench makes things really easy in this respect. Try making one. They're piss easy to weld up. All you need is a pipe wrench and a piece of handle-suitable iron for a handle.
In future, compensate for the banana-ing before it happens. Introduce a downwards compensating bend before you start hammering in the bevels. This will even everything up, and give you a cool forged-in backcut as well. Get a feel for how the metal moves, and it will come naturally.

It would appear that we own the same dremel. How long does your battery last? I gave up using mine and bought a wired one. Just not enough power. =/
Great job on the knife there. The polish turned out quite nice.
