Bottom line, if you're under 10 pounds you're doing great. There's always room for improvement though, right?! Of the people on this forum, I'm admittedly one of the heavier packers--and I thought you packed heavy a few places.
You can only wear so many shirts at once. If you're going to wear a Clutch shirt, you don't need two in the pack. One at the most, but I'd instead wear one and pack a midweight long-sleeve item of some kind. Likewise, one pair of underwear worn and one spare in the pack should be fine even for multi-week outings. (Granted, romance and GF might necessitate extra cleanliness, depending on your situation.)
I never recommend synthetic bags because of their poor durability and more, but you might check out Marmot's Pounder for a 1-pound, inexpensive summer bag.
For water treatment check out Sawyer's inline filter. 1.8 ounces & ~$45; you're at a combined 7+ ounces.
I know you like knives, won't mess with that or the sharpener. (But do you need the evogrip?) Fire-wise, a lighter and a sparklite are all you really need. There's probably overlap in the pocket survival kit and other items you have listed. Check for light options therein... for example, I'd always carried a Storm whistle, but found that it weighs .75 ounces vs .3 ounces for a (louder) Jetscream. You find five or ten tiny items with little weight differences like that and all the sudden you're talking about a quarter pound savings, easy.
A small alky stove would be a sensible addition--a soda can stove and a bit of foil, a water bottle from the gas station and you're looking at two ounces or less to have a basic stove. Can make life a lot easier.
Oh, and the bivy is really heavy. If you wanted to stick w/AMK, their emergency bivy is 3.8 ounces & $15. WM makes an awesome (& durable) VBL at ~4ounces, costs $90.
