TP Tobler

You know how you tear off 3-4 squares of TP, fold into a wad, wipe, fold some more (repeat) and then discard? The effect is that only the two outermost sheets get soiled, thereby wasting more than 30-50% of the sheets you had obtained from the roll in the first place. The usable area keeps getting smaller due to the folding. The rest of the wad is effectively used for 'padding' your TP wad for comfort.

Now, imagine TP not sold in rolls, but rather wedges (think toblerone) with a tapering tip. These pleasantly scented wedges would be replaceable, soft-cored, and sold with varying angles to accommodate diverse crack-ergonomics and (ahem) personal tastes. You buy the starter pack (base + first pack of TP) and refill TP packs. Creative shapes (like the browser web 'finger', or the sharp creased paper models for example) could also be incorporated.

The idea is that the TP sheets are stacked on the apex of this core with a row of tabs for easy removal. Upon use, the wedge is drawn across the faecally soiled nethers, thereby soiling only the topmost sheet. This sheet is removed, and discarded, thereby exposing a fresh sheet. Repeat until hygenically acceptable levels are attained.

Pros: Usage efficiency is greatly improved as all the sheets are used exactly once. The shape of the wedge encourages a civilized 'sliding wipe' action rather than the crude but tempting 'finger dig' method. Comfort is also a plus as you effectively have the stack of TP, not 3-4 sheets as your 'support', and even the last sheet is buffered by the soft reusable base. Hygiene is improved, as your fingers hold the core, not the TP. So stinky finger is thoroughly avoided, leaving the hassle of washing up afterwards moot. Even if the topmost sheet is perforated, you only need to discard as many layers as were damaged and poof! new sheet.

NOTE: Sheets may also be removed from the top of the wedge for more traditional uses (e.g. wiping the seat, you insensitive clod!).
