The other \"blade\" end of the #241 is for standard couplers, also, the blade end has nubs so it can double as a spring pick for inserting small coil springs. To manual uncouple the #118 \u0026amp; #119 coupler with the pointed end of the #241 \"Dual Tool\", first push the cars together where the coupler knuckles compress against each other, insert the pointed end against the \"outside\" of the hooked tip of the knuckle as illustrated (the knuckle is the moving part of the coupler head). As the point slips into the coupler it will push the knuckle past the hook of the opposing knuckle.
