First and foremost - Skilcraft US Government pen, fine point. They write *forever* and I have never had a line bleed or morse code along a ruler. Nice fine lines. My everyday pen. Slightly thicker than you are asking for, but meets the other criteria. Always ready to write. I pulled some 20 year old stock from a storeroom and they started writing right away. No excessive force needed. *cheap*
Second - Zebra F701. Wonderful pen. I've had mine for about 3 years now. Durable and good looking. Finer and better looking ink text and lines. Meets all your criteria and is a joy to hold. All stainless construction.
Third - Fisher space pen, matte black finish. I've had it for 10 years. The ink is a bit smudgy and stays wet for a long time. It's been supplanted by the Zebra. Does not meet criteria 1 or 3. The finish is a bit slippery and fatigues my hand during long sessions. Strong enough to use as a stabbing weapon.
The Zebra and Fisher live in my uniform, even when hung up in the closet. They serve me faithfully and I never let them out of my sight. I'll give away the Skilcrafts all day but get anxious if my "babies" are lent out.
