We all no the specs for the manix2 so I wont add that.it's the 154 cm full spyderedge.this is one my edc's I carry 2 .the street beat for slicing tasks that take a clean cut or finess.the manix 2 for boxes wood plastic wire.this knife will cut threw anything.the spyderedge and ergos of the knife make it cut threw most materials like butter .its just amazing hiw sharp it is easy it is to push threw anything.the serrations are razor sharp and you can keepem sharp with a ceramic hone on the sharpmaker.the way the manix 2 has the blade offset in the handle allows you to cut with out using so much force its a great design.I have the full series set if the manix from the original to the mini all the sprint runs and store store knives.my favorite is still the spyderedge for just raw cutting power it has.I have the first para with the spyderedge and it gets rotated out with the manix2.I wish they made the pm2 in spyderedge I would buy a couple.I like fixed blades for slicing and finer cutting tasks and serrated for shear power but I dont like carrying two sheaths looks stupid so one must be a folder.for self defence the manix 2 serrated will cut threw leather ,jackets,jeans,kevlar and leave a crippling cut on the otherside I personally think it does a better job then a straight edge blade at self defence.it also cab punch threw thin metal with the point of the blade or a body.the blade style lends to many possibilities.for a all around funcional edc under 100$ this bkade cannot be beat.I will put it to test with anyother knife of the price range ir higher in basic cutting, slashing,and self defence.paired with a good straight fixed blade ie "street beat"or a straight edge manix 2 you have a reliable blade for every task.does anyone else love the manix 2 spyderedge or just spyderedge on any knife?thanx for reading
