Beater Blades...I broke em. But that's what their job was, to be used if they broke I don't worry to much about them. Mostly a low end folder for work that I know that will break. I use to use a Gerber Gator Blade for years till I lost it then found it again. I even got one with serrations till it got stolen. I had a few real bad experiences with frame locks and only get them as expecting them to be expendable for light general use.
Now since getting bitten by the knife bug, I have to many Hard Use knives that I can use the proper knife for the job. 5160 for wood chopping batoning for example. One SP-10 I was going to use a a beater blade turned out to be used less than my SP-51s I use for heavy wood work. (I mean HEAVY work). So since it was lightly used I rounded up a few of my duplicate buys and that one and gave a set of knives to my little brother from a nice Gerber Strongarm for a tough smaller knife, RD6 he uses for hunting, the RD Tanto he says is a great middling woods whopper, that SP-10 he likes using it just to use it as his "Beater" now. And the SP-53 I gave him is his serious pack/camp knife. I did get a SP-10 for the beater and in case I forgot to pack the "Main Knife" because well I just like it for a big "Beater" blade.
I did use Buck 110s and Sharades when younger and they were great all round general purpose hard use knives I used, I took care of them so does that make it a beater blade? Well only one Sharade knife survived from not being stolen or idiot relative who borrowed it "Lost" it. That still gets used as much in my smaller knife line up as ever. I find the lock back folders are still best for field small blade tasks, but I do keep a few smaller fixed blades around, I can put up with the "Monstrous" light ounces having a few small back ups. I went with expendable folders after I had some of my former EDCs were "Confiscated" for some reason or another. I figured why let some one steal some good steel performers when they can get just average workable ones?
Now after my Rolling Meandering Ramblings I guess my current "Beater" is a Lansky some thing or other frame lock, then usually a Gerber Gator blade...I always get one or two for that purpose if I remember get one that is. My Gerber Strongarm is the "New Beater" blade I guess for my smaller to middling fixed blades, but if its to tough for my strong arm when needing a shorter blade out comes the BK2, thats what I got that one for. My RD 7s are my most used larger main fixed blades but my RD Tanto is getting more and more of the grunt work. SP-10, the knife I love to have an excuse to use. Really its a big slab of a steel in a freaking big bowie, what not to love not using it full force? Yes i seem to use my SP-51s and SP-53s more often, but that's when I need the work done with the best tool I got at the time.
As I said I got enough knives to spread out the different jobs at differn't locations, and I got a few more multi-purpose knives like the BK-9s with solid hilts and such that gets carried by others so we got atleast two big knife tools in the group when I get dragged along, one is a dedicated chopper among the other tools we bring.
Editicus: I love this thread, seeing real work knives!
