How to Make a Railroad Spike Knife?





Introduction: How to Make a Railroad Spike Knife?

Railroad spike, a special nail widely used in the railway industry, is an important component of rail fastening system. Among the railway system, the railroad spike is usually used to fasten the rail track. Besides fastening, the railroad spike can also be made into some metal artworks such as knife, bottle opener, furniture and so on with reprocessing.

Step 1: Heating the Railroad Spike

Step 2: Forming the Handle

Step 3: Rough Shaping the Blade

Step 4: Drawing Out the Blade

Step 5: Shaping the Blade Outline

Step 6: Forming the Blade Edge

Step 7: Curving the Handle

    they call that the power of forging, it's kinda what this whole instructable is about

    reminds me of improvised trench knives of world war 2 where soldiers would have a trench spike flattened into a double sided blade and have the rest of the bar folded into a hand guard.

    can be found at McMaster - Carr or MSC I believe

    Caseinite A product for case hardening steel. Comes in a can in granular form. just cherry the item to be hardened and stick in a couple times should do the trick. Also known as case hardening. made a cold chisel in junior high metal shop. worked well

    for years. case hardening is surface only. not sure of depth but should work.

    for years.

    Very nice letter opener.

    Unfortunately, that's all it is. RR spikes are classed as low-carbon steel, which means they can't be heat treated, which again means that they can't hold an edge. But nice work.

    2 weeks later, I think of a better "comeback" :-)

    For over 2000 years of bladesmithing history, BRONZE was the very best knife metal available. And it worked quite well.

    In terms of hardness, a good bronze is in the mild steel range.

    agree and disagree, on many levels.

    COMMON railroad spikes(like they use in actual railways) are as you say. Though their edge retention is better than you may expect. Even low carbon, un-hardened steel can hold a pretty good edge for a usable length of time. And in the tradition of boyscout knives everywhere, a quickly dulling knife gives you great practice in sharpening. at least that's MY theory on why they make the official pocket knives out of whatever type of steel(possibly just really hard butter) it is.

    To add fuel to the fire, I know of at least one smith who got a hold of a die set for forging RR spikes and produced them in both 01 and 440 in small quantities, and then made knives from THAT. And also, at least on company in china that was making drop forged "china stainless" knives from barstock, that were then dressed and "sharpened" to LOOK like a hand forged spike knife.

    nice jobe mate. Im a suburbanite but have had some great results using a 20gal drum/concrete spiral forge out in the workshop with a blowtorch.
    raw spikes need a shedload of grinding to be up to scratch though.
    these would make an amazing steak knife set with some filing too!
    definitely got the skills that pay the bills.

    Great concept, beautiful and simple blade, well done!

    I wish I had the equipment and skills necessary to do projects like this. It's a safe bet that my landlord would frown on me setting up a forge in my living room and the neighbors would complain about the constant banging. Blowing glass has always fascinated me too but again we have that forge problem.
