Knives I have personal experience with that have really broad blades include the Spyderco Para Military 2, Benchmade 950 Rift, Spyderco Gayle Bradley, Kershaw Blur, and Cold Steel AK-47. The first three are by far my favorites and I recommend them very highly. From what I've seen the ZT series has really broad blades as well as tons of Spydercos. Look around and see what models you like.
