Lesson 1: How to Make a Railroad Spike Knife | DIY Knife Making: Overview

In this lesson, we meet Aram… a badass, knife-making, epic-beard-wielding blacksmith at Adam's Forge in Los Angeles. Before he jumps into the intracacies that go into knife making he gives us a little background information on himself and Adam's Forge, the only true blacksmithing community in Los Angeles. For Aram, a lifelong knife enthusiast, blacksmithing was a great option for him to learn the craft of bladesmithing. To be able to ‘move metal' well, to mold it into a variety of shapes is what Aram believed would best prepare him for eventually becoming an excellent knife maker. Thus, his journey to Adam's Forge. Aram gives us a little bit of information on the course structure at Adam's Forge and tells us why this schooling community was so beneficial to him.

Lesson 2: How to Make a Railroad Spike Knife | DIY Knife Making: Choosing Your Spikes

Choosing your spikes to use for your knife is a crucial step. Some people prefer to purchase newly manufactured spikes, while others prefer older, rusty looking spikes that give that rustic feel. Regardless, they are quite easy to find on the internet. In this lesson, Aram takes us through his approach for choosing the right kind of spike. From the size, to the color, to the overall structural integrity of the metal, you'll learn all kinds of tips on how to choose a great spike to make a sweet knife. After that, Aram shows us the difference between a ‘full twist' and a ‘half twist' handle so that you can learn how to customize your knife to your liking. And finally he explains why working the metal of a railroad spike is a bit different that normal ‘High Carbon' metals that we find in knives.

In This Video:

• Choosing the right spike
• Rustic v. New spikes
• Full Twist v. Half Twist handles
• What the ‘HC' means on a railroad spike

Lesson 3: How to Make a Railroad Spike Knife | DIY Knife Making: Marking Your Handle

Now that we have chosen our spikes, we are ready to start marking out the specifications of the knife itself. The first step is marking your handle. We all have different hand sizes and personal preferences, so this is an important step to get right to make the knife more than just an ornament. The average railroad spike is about 6 inches in length. BUT it is crucial to keep in mind that it will elongate through the smithing process. We will also go over tips on how to forge a slip guard so that your hand will not slip onto the blade. For Aram, that is the most difficult part of the blade-making process. The final thing this video covers is CRUCIAL!! Safety! Safety! Safety! Tie back your hair, your beard, wear eye protection, gloves, etc, etc… we're dealing with freaking molten metal after all!

In This Video:

• Marking your handle
• Punching your mark v. Using carbon pencil for marking your handle
• The importance of a slip guard

Lesson 4: How to Make a Railroad Spike Knife | DIY Knife Making: Lengthening Your Blade

This video throws us right into the heat. With Aram, our DIY knife making expert, we go through all the preliminary steps to lengthening the blade on what will become your knife. First things first… SAFETY! Once your beards are tucked away and your cool protective goggles are on we're ready to light up the forge, choose the right tongs, and get going. There are options for which tongs are best for making railroad spike knives and Aram gives his advice on which tongs are best. Then, it's time to jump in the fire. First, Aram shows us how to use the peen to elongate and widen the blade portion of the spike. At this point, it's not necessary to choose which side will become the sharp edge of the blade. What matters is getting the blade to the proper length and width. Aram then goes through the process and starts hammering away at the spikes to get them to the proper length.

In This Video:

• Lengthening your blade
• Which tongs to use
• How hot to have your forge
• What color your spike should be for hammering
• Peening your spike
• And more…

 

 

Lesson 5: How to Make a Railroad Spike Knife | DIY Knife Making: Drawing Your Blade Width

Once you have a length that you are happy with, it's time to start drawing out the width. In this video, Aram goes through how to get the proper width for your railroad spike knife. Using the peen, we'll be hammering along the longitudinal axis. Again, temperature is important, so make sure to follow Aram's advice closely… or else you'll just end up with a flimsy knife. And really, who wants that?!?  After he goes over how to widen the blade, Aram spends a little time discussing which hammers he uses and why.

In This Video:

• The width of the blade
• Types of hammers
• And more…

 

 

 

Lesson 6: How to Make a Railroad Spike Knife | DIY Knife Making: Removing Peen Marks

In this lesson, Aram takes out his rounding hammer and removes the peen marks that were made during the lengthening and widening phases. Consequently, we'll also get a little bit of a widening of the blade during this process as well. Aram also talks about why removing the scale is a good idea, unless you are going for the rustic look, in which case the scale will actually be ok to keep on blade. We're getting closer! Keep taking notes so you can be sure to make an epic railroad spike knife.

In This Video:

• Remove the peen marks from lengthening and widening the blade
• Further widening of the blade with the rounding hammer
• The pros and cons of the scale
• And more…

 

Lesson 7: How to Make a Railroad Spike Knife | DIY Knife Making: Setting Your Guard

Setting your guard is a bit of a delicate process, but one that is crucial for the safety of your wielding hand! In this lesson, Aram shows us exactly how to set a guard on our railroad spike knife. This is the next step in the DIY knife making process and will ensure that our hands won't slip into the blade once the knife is complete. There are some important steps that can't be skipped so make sure to pay close attention. Take notes, get your forge going, whatever you have to do to get yourself ready… cause this lesson is quite detailed!

Lesson 8: How to Make a Railroad Spike Knife | DIY Knife Making: Tapering Your Handle

In this lesson, we see Aram taking us through the next step of tapering the handle on our spike knives. This step is important to taper the indentation that we made by setting our guard. So rather than have a large indentation between the handle and the blade, what we want to see is a gradual tapering from the handle into the blade, while still preserving the protection that the guard provides. This is a process that takes  some time to get right but it's really not that difficult. Just pay attention to our master blacksmith, Aram, and you'll forging in no time!
