The fact that any of these expedient saws work at all is a small miracle. Traditional crosscut saws came in several tooth variations for both hard and soft woods, with rakers to remove chips and arched bodies for stroking smoothness. Then they had to be periodically sharpened and the teeth "set" with the radius maintained. A saw out of tune wasn't called a "misery whip" for nothing! If a larger wood saw is required ; Stefan's Sandvic is excellent, as is a simple bow saw. A one man crosscut ( assymetric blade, accessory handle for two man ops) is very stowable, but the maintenance is again problematical. I just carry spare bowsaw blades and fashion a wood handle out of a green sapling.
