I’ve wanted to review the EJack Knife for several years, and it was about time I found out what this powerhouse board was all about! Lib Tech and Eric Jackson really created a visually impressive board, the base graphics stand out and make this board turn heads on the mountain. Initially this board feels very stiff, and I had to adjust my bindings to be more centered for my riding style. After a few days, as it broke in, I felt very comfortable on the EJack Knife. Carving up groomers is a blast on this board and it will want to take you faster and faster the more you ride it. It has tons of pop, so ollies off of natural terrain will have tons of power, I will note you can, and have to, load up the tail to initiate the ollie on this board due to it’s slight rocker and large camber zones. In powder I felt this board was a lot of fun, it floated well and in choppy terrain and moguls it was easy to maneuver. The Magne-Traction on this board really helps you hold an edge in icy conditions, and it rides well switch too. I really liked this board after several days on it, it is powerful and is geared toward the advanced to expert rider. The EJack Knife would be a good choice for the advanced to expert rider looking for a board that is snappy and wants you to push it to the limit for all mountain riding.

Overall Impressions:

I had to get used to this board, it’s a bit stiffer than my normal ride. I feel the EJack Knife is for the rider that prefers a less forgiving, yet powerful, board that has massive pop and wants to just rip it fast through powder or on a groomer. This board will hold an edge heelside or toeside easily through any condition. It’s a true backcountry option as it was built for Eric Jackson and it is meant for big mountain riders. It’s a fun board that’ll rip it anywhere, especially in the side or backcountry

This board increases greatly in stiffness if you go up in size (this has been pointed out in other reviews as well) If you ride a 157 get the 157 if you ride a 154 ride a 154 don’t size up unless you’re aware of that.

  1. Hi Chris,
    I agree with your review and I found that the Ejack Knife was way stiffer that I expected. Advertised as a 6 out of 10 I’ll say it’s the same stiffness as my Custom X of the same size… I bought the 154cm as a daily driver too replace the Custom X with a more directional and tapered option. I was expecting the Ejack to be easier on my body for long days on hill. Being a light rider (145lbs) it was too tiring to ride 6 days in a row when I’m in vacations. I rode it only 2 days and resale it. Reading you I probably should kept it and wait that it brakes in. But I doubt it would ever reach a 6 out of 10…
    The shape, way it carves and jumps is otherwise really nice. It was good in the kicker line in the park with a lot of stability on the way in and ample pop. I had the chance to test it in powder too and I agree that it float really well for an all mountain board. I will add that it’s the kind of board that is efficient to Ollie in powder which is really satisfying.
    The carving and speed is crazy with the camber + magne traction. One thing I didn’t like about it was the confort on bumpy terrain. I could feel the nose not really flexing when going over bumps and kind of slowing down the board. it was less comfy than my Custom X.
