You guys are probably way ahead of me on this but I just broke down and purchased a Fast Bucksaw saw and a Littlbug senior stove. Wow!! Both are great additions to my camping gear.
We all have tools that do the work, but only occasionally do you find a tool that gives you pleasure using it; I would suggest that the Fast Bucksaw is one of the few. First and foremost it cuts like a dream, but then as you get to opening and closing it it becomes evident just how much thought has gone into refining the design. Beautiful work!
Some time ago I made a twig stove from one of those chimney charcoal briquet lighter things that you can find in the hardware stores. It works well and I've had a lot of fun fooling with it. But no matter how well I like it, it is heavy and no way will it collapse and pack neatly. So after looking at all the offerings on the market, I bought the littlbug senior.  It's the larger of the two and well made with stainless steel that doesn't feel the least bit flimsy when you get it set up. For me that was one of the most important considerations; don't want the fire escaping or for me to get scalded with a tipped over pot of boiling water. As it comes, it has no bottom to hold the fire so I'm experimenting with various configurations of cake pans and what not on the bottom to hold the fire and more or less insulate the ground from the heat. A work in progress.
What I can tell you so far is that the stove shields the fire from the wind well and would allow me to have a fire under conditions that I wouldn't dare have a open campfire. I'm learning what size of sticks/chunks of wood will produce a sustainable fire with out the necessity of hovering over it all the time. The pot supports allow you room to feed the fire without removing the pot most times. There is a carrying case that you must buy extra but I'm glad I did because it allows all four parts of the stove to be packed neatly and keeps the soot controlled.
All in all I'm glad I got both of the Fast Bucksaw and the Littlbug sn. stove and if your looking for a saw or a stove I recommend them.
Best Wishes, Rob
