A non-piercing, non-thrusting weapon will never stop a charge. It can only slow it down. If it slows down the charge enough, the charger won't reach you and will have to do something else with his Move and Attack or All-Out Attack action.

Let's take an example: a ST10, DX 15 guy in kevlar (DR 12/5) performs a Move and Attack on your character from 3 yards away while you're on a Wait to attack the first guy to get in range with your hand axe. The attacker has Move 6. He spends 2 MPs to close to 1 yard and triggers your wait. You hit, he fails to defend, and you do 8 basic damage to him. Since it's cutting damage, it's all absorbed by his DR and becomes knockback, sending him back 1 yard. He makes his DX check to avoid falling and spends another MP to close back to 1 yard and then loses the contest of ST with you. He spends 2 more MP to back up slightly and come from another direction. With his last MP, he enters your hex and attempts his slam.

So even though you hit him and did knockback, you failed to end his turn by stunning him or knocking him over and he had enough movement to enter your hex.

Example 2: same guy, but he started 5 yards out. When you knock him back one hex, he fails to have enough movement to enter your hex and must attempt his attack maneuver from 1 hex away by making a Wild Swing. Sucks to be him.

Example 3: same guy starts 3 hexes away but forgets to wear his kevlar. You don't knock him back, but you do inflict a major wound, stunning him. He falls down and loses the rest of his turn. Even if he resisted the major wound, he's below 1/3 HP and is slowed to half Move and can't enter your hex if he loses the contest of ST, resolving the same as Example 2.

I think that's all the options: hit but failure to stop; hit and slow enough to prevent a Slam; and hit and stunned to prevent his attack. Okay, there's a fourth option where you miss him or he defends against your Wait but that's pretty obvious.
