If someone had an item that is significant upgrade, that doesn't gimp my other stats - I'de be intersted in talking.
Get away from a Knife altogether. You are a bear doc which deals damage off your weapon damage and not your attack speed. You are searching for the wrong item if you have been stuck on searching for CK's. Start searching for maces, spears, and axes. The lower aps will increase the bear dmg while lowering your aps which compensates for not having mana regen on your weapon.
Unless you are set on just wanting your doc to hold a knife... then you are outta luck because your knife is a pretty good one.
i.e. My weapon ( http://imgur.com/DmyMJLn ) would give you 10k dps unbuffed with 10 AR (from int)
My friend's weapon ( http://imgur.com/oFlgNwf ) will give you 14.2k dps with 13 AR (from int)
