I always have a SAK in pocket,and if touring/going on longer rides,a Gerber multi-tool (Suspension model I think). If gravel/rail trail/bike-packing type camping,I always carry my Becker BK2. Not light by any means for it's size (I'm not a weight-fixated rider tho),but it's nigh indestructible,and easily sharpened. I would trust my life to that blade in a survival situation if one arose (I'm a big Becker BK series fan too tho,and I always have my BK11 neck knife around/handy too )
