I do both, and don't find either difficult, but you can crochet without using a hook. After I watched the Knitty Gritty where...darn it, there went her name again; she's far more famous for crochet than knitting--demonstrate what she did when she wanted to crochet a granny square and had no hook, it made perfect sense.
I'm trying to write up some directions now, but have to find time to sit down with the yarn and see if they're right. If they are, you're not limited to single crochet edgings. You could do any combination of crochet stitches AND any combination of knit stitches, even in the same row. If any of you can try it, see if this works for a sc edging. I THINK it amounts to--
Row 1: knit the first stitch on your bind-off row,
knit the second stitch,
knit the two loops on your right-hand needle together, and keep going across.
Row 2 (you should have only one loop left on your needle:
Knit that stitch. Pick up the next stitch (i.e. draw up a loop) and knit the two stitches together. Keep going all the way across, then finish off.
