I modify/refurbish/sharpen hatchets, knives, swords, machetes in my retirement. So, before you seek out a quality item manufacturer, you need to ask yourself a number of questions:
1. What kind of sheath? You probably do not want to store it in a leather sheath. Give some moisture and chemicals that might be used in treating the leather, you might be welcoming rust. So, if you choose leather, you need to find a different and cloth material in which to store it.
2. If I am going to wear the sword within a sheath, where do I carry it? For my Japanese units, I wanted across the backpack/across the back/over the shoulder option. This meant finding a guy who makes Japanese wooden sword sheaths and designing one for the placement.
3. If you read reviews and conclude that most KNIFE sheaths issued with factory knives are bad, just wait until you learn that virtually all after market sword sheaths have to be custom made.
stabbing vs. slashing blade
4. Why are swords carried by horseback riders curved for slashing and why are European swords for ground fighting straight bladed most of the time? You need to think about the answers. Obviously, the design is fitted to the desired application. You are not going to have both options perfectly incorporated into a blade.
5. Carrying a sword when mounted is awesome in the movies. I watched Errol Flynn movies for free on t.v. when I was a kid. The reality is that when Custer went into battle none of the soldiers were carrying a sabre. No longer functional in battle. In fact, except for the cossacks, troops would routinely dismount and go into battle with firearms. One soldier could control 4 horses while the other troopers went into battle.
6. I do have traditional sabres with original sheaths. In 2019, you are not going to be walking very far with them, except in re-enactments.
metal on metal - or why people with decent swords use wooden swords or bamboo swords or even rubber swords in practice.
7. Reflect on what happens to sword blades if you hit metal on metal.
I want you to watch this video of a grand master using a metal sword. To the untrained eye, it is a waste of time - he isn't hitting anything. To the trained, the man is master of fluid movement. The skill in drawing, presenting, and securing a sword doesn't come with the sword that is purchased. I had instruction in khuri knife fighting and saw a woman seriously cut herself and go to hospital just drawing the knife! You are wasting your money if you buy a quality sword before working on the skills.
8. At the end of a non-knife class, an instructor asked me to retrieve a practice escrima stick from my car. I brought it and he promptly broke it. I then said I would go and get the stick that I kept in the car that I had made. I presented it and he made no attempt to break it. I made it out of cast iron black water pipe.
9. If you want to chop around with a long piece of metal, then get an inexpensive machete. They really work in practice. The challenge to me is making over the shoulder/across the back sheath set ups.
