Hi, i have a boker afd,ive had it since it came out a few years ago. its got an s60 blade steel, the efd(escrima folding dagger) has a 440c blade,pointier butt,holes in the guards,about 5"black aluminum handle,different grooves in the handles. its got a big,chunky handle,very wide & flat. the 4" blade isnt the best for everyday utility, but its still pretty cool & unique.the liner locks at the 1st part of the blade shank,& it can be partialy flipped open using one of the guards.deep pocket clip keeps it low in the pocket.it carries well,too for a big folder.its a bit expensive, i got the afd for 112.00 when it first came out,got a deal on it.its much more, now. the escrima is around 110-150 or so,you should do a google search on it.the boker turbine is a much more practical knife, i have that one,too.has the x15 blade,flipper,aluminum handle,too.i really like the turbine,more than the afd/escrima.
