The Flat Rasp – "A weapon of hoof mass destruction"
The familiar ”flat rasp” can be found in the tool box of any professional farrier or barefoot trimmer, including DIY horse owners. It is commonly the most deployed tool in all trimming camps, requiring less skill to manipulate than the hoof nipper (see my previous post). We see the farrier trying to get the bottom of hoof wall flattened from heel to toe for the horseshoe, and not infrequently rasping the toe wall back to the shoe (a "no no"), while the barefooter finds the rasp far less expensive to replace than the dull, chipped blades of the abused hoof nipper. Horse owners often use the rasp to "touch up" frayed edges of the hoof wall in between visits of their professional provider. It seems everyone is in on the action.
While all this rasping is going on, the Natural Hoof Care (NHC) Practitioner confirmed to a genuine Natural Trim may not use the flat rasp at all. This was the case with me. In fact, my flat rasp spent most of its time in the tool caddy of my tripod hoof stand! Some of my more astute clients noticed this, several asking, “Isn’t that the same flat rasp you were using a year or two ago?” Guilty as charged! The flat rasp's demotion in the hierarchy of trimming tools can be traced to the wild horse hoof model and the advent of new trimming tools designed specifically for the Natural Trim.
Flat rasp - collision with the wild horse hoof!
The very first day I spent at the Litchfield, California BLM corrals 43 years ago (1982) was a total wash out. I remember saying to myself with a farrier's hoof gauge in hand to put on the first wild hoof, "But there’s nothing flat to put the hoof gauge on.” I knew then and there that my days as a farrier freely wielding a flat rasp were numbered. It was just a matter of when.
I also came to see the flat rasp as a potential “weapon of hoof mass destruction.” In fact, it can be easily weaponized by thinning the outer wall to make it look “pretty,” rasping the hoof wall back to the shoe, rasping off unsightly stress waves due to laminitis, getting rid of flare, and over-trimming the Mustang Roll. These are all examples of wall resection that compromise the hoof’s stability and natural growth patterns. In other words, reasons for keeping the flat rasp in the tool caddy.
Don't toss it in the recycling bin, there's still a place for the flat rasp as a Natural Trim tool!
Having said this, the flat rasp still has its place, albeit in a much more limited way. So, it should still be homed in the tool caddy of every NHC Practitioner in case it is needed. The flat rasp now serves the Natural Trim in three important ways: Marking the hooves for cut-lines (Navigational Landmarks), lightly thinning the toe wall's support pillar if it needs it, and using the handle of the rasp to rotate the tool caddy around to access trimming tools during sequencing.
Final thoughts
Today, new and unprecedented tools have arrived to relieve the flat rasp of what it should not and need not do in the Natural Trim. Relegating the flat rasp to the three tasks above are all part of the skill set of the NHC Practitioner, who, in fact, is extending its life into the realm of the unimaginable.
