Every year, John and I bring dozens of new Gundam models into the world. From Universal Century to Future Century, from Master Grade to No Grade, our house is filled with them!

But the not-so-funny thing is, you can clearly tell which ones we built first, and which ones we’ve built more recently. They’re a little wobbly on their feet, a little rough around the edges. That’s because, as we started to wise up to the world of Gunpla, we began to add tools to our Gundam building arsenal.

I don’t think you need to drop a lot of money in order to build a nice looking, polished, sturdy Gundam model. But I do think that a few tools can take you a long way.

Here are our picks for building the perfect Gundam model, at any level.

Side Cutters

Gunpla modeling is certainly easier today than it’s ever been, and all you actually need to get started is a basic High Grade kit (here are my recommendations for beginners) and basic wire side cutters, like the kind that’s used for jewelry, to cut out the pieces.


However, getting a pair of side cutters specifically designed for Gunpla and modeling can seriously step up your building. In the photo, I’m using Tamiya side cutters, which were designed for hobbyists, not jewelers. They’re stronger for when I’m cutting through even big pieces of plastic.

When choosing a pair of side cutters, pick a pair that feels comfortable in your grip, because you will be using them more than any other Gunpla tool! You may also want to choose multiple pairs that you can alternate between depending on the project. For example, I love how my Tamiya cutters are up to the task of even the thickest sprues, but I also love my God Hands, delicate though they may be, for their precise snips and great detail work.

Here are some of our recommendations for side cutters. For more explanation about why we picked these models, check out The Best Tools for Gunpla, Ranked.:

Hobby or X-Acto Knife

Next, I use a hobby knife for cutting down the nub that gets inevitably left over after I cut out a piece. In the photo, I’m using a Tamiya Precision Cutter, which is retractable so you can control how much of the blade is poking out at a time—a great safety and control feature.


There are two main kinds of hobby knives—retractable and replaceable. If you have a replaceable knife, like an X-Acto knife, you can simply trade out the blade with a new one when it gets dull.

It’s not just that your Gunpla will look better if you use a hobby knife. It’s also that the pieces will fit together more smoothly without any extra friction. It’s just one extra step, but it makes a big difference.

Here are some recommendations for hobby knives:

I’ve found that when I try and apply stickers to Gunpla manually, the oil on my fingers makes the stickers less sticky, so now I apply them with tweezers.


Tweezers also allow me more precision than when I’m using my big, stubby fingers—I can more easily line up where I need the sticker to go. I suggest using angled tweezers for precisely this reason. That way, they stay out of the way while you’re gauging the exact positioning of a sticker.

Here are some of our recommendations for tweezers for Gunpla:

Gundam Markers for Inking

As pictured above, you can buy Gundam-brand markers specifically for inking your Gunpla, most frequently during panel lining. The fine tip of the pen is perfect for getting in the ridges of Gunpla parts so you can add lifelike detail and contrast. You can also read our panel lining 101 tutorial for more detail on how to do that perfectly.

Here are some of our recommendations for markers. For more explanation about why we picked these markers, check out The Best Tools for Gunpla, Ranked.

In many cases, you can buy all of the tools I already listed in one single kit for much less than it’d cost to buy them individually. These set also comes with some stuff you probably don’t need yet, like a metal file for sanding down parts, that will be useful when you want to get more advanced.
