Well, let me start by going over what makes a custom knife valuable.

Like all other collectibles, custom knives vary in price, beauty and quality. One of the easiest ways to determine the quality of a custom knife is to find out who the knifemaker is.

Just like with cars, the name of the knifemaker matters. Tim Herman, as an example commands a great deal of respect in the custom knife making world.

Next, you should take close note of the handle of the knife. Of course, you want to see a custom knife handle and not one that looks like it has been mass produced.

There are many materials that custom knife handles can be made from. These handles are nothing like the ones you are used to seeing on your typical household knives.

Some of the engraving in these handles, alone, will make the knife worth buying. Some custom knives have pictures of cars or people carved right into them. It's absolutely amazing.

Once you have examined the handle, it's time for you to look at the blade.

Just like the handle, the blades that make up custom knives vary greatly. From material to quality to length and several other categories.

Although I won't get into it here, knowing how to determine the value and quality of the blade can make or break the deal.

Collecting custom knives is much more an art than a science. However, there is a formula that you can use to gauge a large part of your decision.

Knifemaker, handle, and blade. The three most important parts of a custom knife. If you are unhappy with any of these three, get out of the deal.

But what happens when you are happy with what you see, now what do you do?

At this point, it's time to look at the subtle details of the knife. Is it in mint condition? Can you see any obvious wear and tear on the blade or handle? Is there a certificate to prove that the knifemaker actually did make the knife?

Make sure to get all you questions and concerns answered. A custom knife is a large investment, and one that will last a lifetime. Don't allow yourself to be pressured into a purchase that you are not 100% sure about.

Of course, if you are a trader of custom knives, than price is your determining factor. Regardless of the condition of the knife, if you know you can sell it for $1,000 you would be happy to buy it for $600.

If that doesn't make sense, it's time for you to get out of the custom knife trading business.
