Here is a knife combo pack with interchangeable blades. It has a wood saw in the pack. It’s made by Kerskaw, it’s called a Blade Trader. It has 6-blades, fish blade, bone saw, wood saw, 2 regular blades (one curved, one strait) and what looks to be a bread cutting blade. I’ve had it for going on 20 + years. I’ve mostly only ever use the wood saw on it. It also has a zip-up case.

It’s not something you are going to hack through the jungle with, but it does work well sawing wood.


They also made a smaller version called a Jr Blade Trader, it had 3-blades.

I don’t know if either one is still made today.
