The Lib Tech Ejack Knife is a tapered, directional snowboard designed for advanced to expert riders who love to carve, bomb hills, and catch air.

One other thing to mention is Lib Tech / Gun / Mervin has been altering the construction process since the 90’s to make boards and that is longer than most brands have been around. There is literally no other brand even close to this level of green construction. This is ironic because they don’t scream green like other brands do. This overall construction makes The Lib Tech Ejack Knife is a nice balance between weight and durability. It’s medium and maybe a touch on the heavy side of medium but most won’t care.

Sizing and Feel
The 157 Lib Tech Ejack Knife fit really well for my specs and while I can handle the 159 no problem I really felt comfortable with the 157 and that would be the size I want to buy. Sizing is all about balancing what fits your boot size (most important), weight (second most important) and height (third most important) for how you like to ride. Size down for more control and size up for more speed/stability/carving power.
On snow, I felt like the Lib Tech Ejack Knife was medium-medium stiff.
Edge Hold and Turn Initiation
The Lib Tech Ejack Knife seemed to change up the edge hold technology a little bit. Really strong grip that handles hard days well. All this camber and their middle mag (.5MTX I think) worked well together to provide a lot of grip. The turn initiation of the Lib Tech Ejack Knife was medium-fast bordering on fast for me. It went wherever I needed it to go and while it feels like there’s more tail behind you in tight spots, like in tight tree lines that are uneven, it’ll be a little catchy. Not the smoothest making hard rights or hard lefts, but it’ll slalom really well between the trees.
What I liked about this board is the neutrality it had when it comes to weighting your turns. Sometimes a board with eight millimeters of taper feels like it needs a lot more weight on the back foot. This felt like it needed little to no back foot weight on the turns. So I think any way you want to weight your turns will be fine with this board, even though it might lean a touch towards center to back foot weighted turners.
The Lib Tech EJack Knife likes a straight line but can also go from edge to edge rather well. The healthy bow of camber that makes this locked in and full of consequence if you fuck up makes it a joy to turn. The spring out of each turn was so rewarding and fun. Loved laying it over and seeing what it can do.

Powder Performance
I didn’t get this new Lib Tech Ejack Knife board in powder, but I got the old one in about a foot and a half of thick Pacific Northwest powder, and I felt like it took a good bit of work, especially in low-angle powder. If you know how to ride camber in powder, this is going to be fine for you.
The Lib Tech EJack Knife has a tapered tail, and you can get a 6″ difference between nose and tail and 3″ back from the center of the board with a 22.75″ stance width. So, in about 1 foot to 1.5 feet of PNW powder, I felt like I had to be vigilant with my back foot pressure to keep that nose up, and I thought this would float better. It was a bit off for where I’d like it to be for powder riding these days, with all the amazing hybrid shapes with more float. If this were the all-camber 2000’s, I would have been fine with it and felt it would be better than many rides out there. If you like camber boards in powder, you will find this a very good ride.
If you like to straight line and point it, the Lib Tech Ejack Knife will do a really good job for what this is.
Jumps and Freestyle
This tracks into a jump really well, feels much more centered than you would think for being one inch back on sidecut. It can track into a complicated side hit really well, launch off it and land really well, too. This is a great board for riding pipe.

The Lib Tech EJack Knife surprised us here. It’s no true twin but it did much better than we thought a tapered directional board like this would be. If you are all about a strong,, snappy ollie, there will be lots of air in return.
Pros:
- Excellent edge hold on hardpack
- Stable at high speeds
- Poppy and energetic flex
- Durable construction
Cons:
- Requires more effort in deep powder
- Less forgiving than hybrid boards
Summary:
And overall, I think the Ejack Knife is a great board. It’s highly recommendable for people who love to turn, love to get air, might ride the pipe on occasion, want a one-board quiver for just about everything, see a lot of hard icy snow days, but don’t want a board that grabs in soft snow. I personally vibed with this board and was surprised at how little it’s changed over the years. It’s a very aggressive board that requires you to be on your game at all times and doesn’t float super well in powder. It also rides almost like a double-ender on groomers, and you don’t feel the taper as much as you would with boards like the Gnu Mullair.
So all in all the Lib Tech EJack Knife is a great board for those that love full camber rides.
Additional Notes
The Lib Tech Ejack Knife has 60% Aspen / 40% Palownia Wood Core with Birch Internal Sidewalls wrapped in a Bi-Ax / Tri-Ax with Basalt Alloy sprinkled in the mix. Then there is an eco-sublimated top sheet that holds up well despite the fact its on the easier side to scuff. The UHMW Exterior Sidewalls continue on from the edges and then wrap the whole board. I’ve found that overall the protection from UHMW is better than most boards with steel wraps from tip/tail and it makes it a little lighter too.
So when it comes to base glide, it felt fine on the firm snow I tested this on but most bases do. In the past when I extensively tested the Ejack Knife in all conditions I found it wasn’t as fast as many bases I compared it to but it didn’t need to be waxed a lot and it feels stronger/more durable than the knife Cut Sintered bases on many Lib Tech / Gnu boards these days. I’d like to test this more but I think most people will be ok with this.
The Lib Tech EJack Knife is one of those boards that shines on hard snow and loves to bomb and carve.

Personal Experiences:
Coming for two decades of Burton Customs, I gave Lib Tech a try with this one, as I felt somehow limited with the Custom in the backcountry and on Icy snow. And it was a great choice. This board kills it on groomers and in the trees, very easy to carve and very quickly on an edge.
The flex is perfect for my needs, stiff but still playfull, this thing loves to take off. Very reliable for carving, riding switch out of a reverse carve is super smooth for a directional camber. Feeling very secure as well in the bumpy backcountry. For deep days I still take my K2 Cool Bean or my Jones Flagship over this one, but every other day they stay in the quiver. My only complain is that they didn't put a sintered base on this one, if they had, I would have doubled this beauty for sure, as it perfectly fits my needs.
Just bought the 159 Lib E Jack Knife a few weeks back and I'm STOKED!! 7 days on this board so far and all of them in DEEP powder. If you are an older gentleman that lives for the positive pressure that comes from pushing hard against an aggressively cambered snowboard, this is your sled! I had no problems floating this in the deep stuff as long as I wasn't in too flat an area. Unfortunately (or fortunately I suppose), I encountered very few groomers or flattened groomed trails until the end of the day's riding when I was heading in from slaying pow, but the board felt great on edge there and dealt with the chunder in those zones well too.
I'm am not a jib guy, but I do like to flick 180s and 360s here and there off the flats or small natural hits and they felt great with this board. It feels pretty quick edge to edge and has a very powerful engine for carving and a punchy, positive pop with that deep camber. I think this is going to be my new daily driver from speedy fresh groomers to moderate /large amounts of pow.
Well done Lib and Eric Jackson.
Hard to break away from Lib once you are riding them.
