My first thought was to make a fighter with the highest AB possible, while relying on 0 buffs or UMD.

12f/8WM/10Dervish
Weapon can be any slashing, so Longsword is a good alternative. You can even Katana if you want to drop Luck of Heroes.
Longsword
Pros
-Gets vamp +2, so good
Cons
-Lower crit range
Intuitive strike = One Weapon
Final Stats (with items): Str-32 Dex-18 Con-14 Int-14 Wis-14 Cha-6
Max unbuffed AB 61:30(base)+11(Str)+4(enhancement)+1(WM)+6(fighter feats)+5(Dervish Dance)+4(1d4 One Weapon)
61/56/51/46/41/36, -6 for ICE would still be...
55/50/45/40/35/30
Total Damage 42.5: 5(2d4)+4(enhancement)+3.5(1d6 cold)+16(str)+6(fighter feats)+5(Dervish Dance)+7(Thousand Cuts)
Base AC 44:10(base)+10(+4mithril chain)+4(dex)+3(Dervish)+3(tumble)+12(nat/def/dodge)+1(LoH)+1(One Weapon)
AC with ICE: 50
Other Pros
-Saves are mediocre (but not terrible) with base 16/22/16 assuming only +3 stat items
-Gets maxed Listen
-No UMD annoying dispelling issues
Cons
-Saves are mediocre with no spellcraft or access to UMD protection.
-No able learner and crappy skills for 2/3rd of your levels (fighter and WM skills are bad)
-No UMD to balance out weakness
-Dervish Goodies don't show up til later epics
-Dervish Dance wont last most of the time until final levels
-Thousand Cuts is not able to be up all the time
For a more defensive approach, you can swap the 10 Dervish for 10 Anointed Knight or Warrior of Darkness.
Pros
-Higher saves (Iron will, max Spellcraft so +6 to all saves against spells)
-Can get Steadfast Determination (can also move out of wisdom and into con to add a little HP and an extra 1-2 fort/will)
-Higher AC (Get to run a shield)
-Two more strength from the two bonus feats from AK, bumping IKD and negating some of the ab/damage loss
-Gets Heal
-3dr (not really that great, but when coupled with higher AC and if you go longsword for vamp, you can get a little hardiness)
Cons
-Lower AB and damage from dervish loss and no one weapon bonus, also if using a shield no 1.5 str damage
-No spotting skill
-Tighter feat management, no free spring attack and have to take iron will, and will want to take SFD seeing as you get a free toughness, but that then requires you to take 4 levels of AK/WoD before 20.
-Shields are lame. (I've been playing a lot of fire emblem and my idea of a swordmaster uses only a sword)
Of course, if you were looking for something a little more balanced, you can do something with lower AB base and fit something like rogue or whirling dervish. You'll lose out on some fighter feats (ie AB and damage), have stricter feat selection (especially because you will either have to push back WM into high epics or you will have to take a chunk of fighter feats at epic levels), and have lower strength as your epic feats are better spent on things like expose weakness. In return you get expose weakness, evasion, and a lot of skills including UMD.
