Think about what it is that you are actually selling. I know that seems vague, but its something I thought about when helping a band put together an album. The packaging does say something about who you are, and how you view your product. Some guys sell an edge, some a status symbol, some an "investment" and some an identity.
Packaging that is overdone, or is in stark contrast to your brand (the irony of a US made knife inside a made in China pouch) will come off as a bit tryhard. GEC and Helle paper tubes let the knife do the talking, even though they are often collected knives, they are users, where as there are brands that would be more suited to a wood display case even if they were tough as nails knives, because that's the brand identity. It also depends on who your main customer is. If he's a guy with a four rack watch winder and a carbon fiber EDC dump tray, you might go with something different than for a guy who's corrosion prevention method is the used oil soaking through his pant leg. Nothing wrong with either, but they will appreciate different things. Your insta link wasn't working for me, so I'm not sure which would be the way to go.
Apple packaging is smart looking, economical and ecological-minded. They know most people are going to throw it away.
These two posts are spot on. As someone who's been around design and marketing my entire professional life, and whose job it is to make someone else's product look good, let me tell you,
packaging matters.
It makes a phycological connection between your customer and your product. It's their first impression they have of you when they receive their knife - not the one they saw online - not the one the handled in the store - but
their knife! If you packaging looks and feels cheap, it sets a tone. If it looks like you put some effort into the packing, they will make the connection that effort went into the final product.
Look at other, higher end products, and how they are packaged. Sunglasses, watches, personal electronics.... all of them come in something that makes a statement that says "this is a product worthy of more than just blister packs and cheap cardboard". Even if it's just subtle and inexpensive.
Someone mentioned Apple, and they are the prime example. The box my new work computer was shipped in is engineered around the computer. Instead of styrofoam inserts, there's pressure molded compressed cardboard to hold everything in place. The power cord is in a separate box, instead of just wire tied into a plastic bag. And that box, along with the one for the keyboard and paperwork, sits in its own molded in spot. Even the coating and print quality on the box looks and feels nice. It would still be a great computer in a cheap box with styrofoam, but you feel more confident about how Apple feels about its product when it's packaged like such.
I'm not suggesting you go all out, but definitely put some effort of some sort into the packaging. Spyderco' may just come in a cardboard box, but it's made from quality stock, and the printing and coating is nicely done. People notice things like that, even if they don't realize it.
What you use is up to you. A pelican case, magnetic box, sunglass bag, wooden 'cigar' box, pouch, or some combination can all work. Just figure out what you want the perception of your knives to be, and let that dictate the style. And it doesn't have to be expensive, but just look and feel of quality.
