There's a big difference between "trimming", "stripping" and "clipping". I assume by trimming you mean clipping, as that's what supposedly ruins the coat. If you just trim certain areas with thinning scissors then this won't ruin the coat.
My local groomers does their "hand" stripping using a coat king, so not strictly hand stripping, but the effect is similar (although the coat king does tear the hair a bit).
I'm planning to use the coat king and scissors, and not have my dog clipped. I won't show him, but his coat should still look okay.
