To tag on, what's wrong with plain ol' cat or cp?

dd can do seek, skip, re-block. It's unusual to need the features but they exist for good reasons. I used dd to transfer 4.1BSD release tapes to a vax 11/720 via rl02 10meg pack and reconstruct the chunks on the receive side, long ago.

ddrescue will do this for you automatically to recover from a bad block.
