a removable cover comprising a bottom surface comprising a first end and a second end, the first end positioned over the cutting end and securing the blade.
2. The manual skiver of claim 1 , the bottom surface of the cover comprising a first surface and a second surface offset from the first surface, the second surface positioned over the blade and spaced apart from the blade.
3. The manual skiver of claim 1 , the shim positioned under the cutting end.
4. The manual skiver of claim 1 , the body comprising pins on the top surface, the blade comprising cavities aligned with the pins.
5. The manual skiver of claim 1 further comprising an opening in the first end of the removable cover that allows skived material to exit the manual skiver.
6. The manual skiver of claim 1 wherein the predetermined cross section is a semi-circle.
7. A manual skiver, which comprises:
a body having front and back ends and top and bottom surfaces;
the bottom surface of said body being substantially planar adjacent to the front end thereof;
said body including a longitudinal recess of predetermined cross section in the bottom surface thereof;
said body including an opening extending between the top and bottom surfaces thereof and intersecting the recess of said body;
a blade disposed in the body, the blade comprising a cutting end comprising a cutting edge, the cutting edge disposed in the opening; and
a removable cover comprising a bottom surface comprising a first end and a second end, the first end positioned over the cutting end and securing the blade;
further comprising a mount, comprising:
a base;
side walls extending around the base with an opening at the rear of the base; and
a slidable jaw positioned within the side walls at the front of the base;
wherein the manual skiver is positioned between the slideable jaw and the rear of the base.
8. The manual skiver of claim 7 wherein a rear facing surface of the slidable jaw is sloped.
9. The manual skiver of claim 8 further comprising a magnet positioned in the base.
10. A skiver comprising:
a body comprising a top surface and a bottom surface, the bottom surface comprising a longitudinal recess, the top surface defining a blade recess, the body comprising an opening between the longitudinal recess and the blade recess;
a blade oriented in the blade recess, the blade comprising a cutting edge, a portion of the cutting edge positioned in the opening;
a shim adjacent to the blade, the shim comprising a notch positioned in the opening; and
a cover attached to the body, the cover comprising a lower surface;
wherein the top surface of the body and the lower surface of the cover secure the blade directly adjacent to the cutting edge.
11. The skiver of claim 10 , the body comprising an alignment pin, the shim engaging the alignment pin.
12. The skiver of claim 11 , the blade comprising a notch, the alignment pin oriented in the notch.
13. The skiver of claim 11 , the body comprising a second alignment pin, the cover positioned between the alignment pin and the second alignment pin.
14. The skiver of claim 10 , the top surface of the body and the lower surface of the cover securing the blade at a first location to a first side of the opening and at a second location to a second side of the opening.
15. The skiver of claim 10 , the opening comprising a body opening, the cover comprising a cover opening, the cover opening aligned with the body opening.
16. The skiver of claim 10 , the blade recess comprising a first portion and a second portion offset from the first portion.
17. The skiver of claim 16 , the blade comprising a back portion opposite the cutting edge, the back portion oriented in the second portion of the blade recess.
18. The skiver of claim 10 , the lower surface of the cover comprising a first portion and a second portion offset from the first portion, the first portion contacting the blade, the second portion positioned over the blade and spaced apart from the blade.
