Delicious, fragrant Apple-pear. And vitamins not deprived. But with the safety of these fruits until next harvest problems, and sometimes considerable. But out drying, pickles jam and other methods of conservation. And the value of harvested products for future use, according to gourmets, will increase tremendously if the fruit is pre-cored. A normal knife is here ineffective as a commercially available special device. But the self-made pruner, dubbed my home “guillotine”, is beyond all praise.

Notched blades for such shears are made of scraps of galvanized sheet steel 0,5…0,8 mm, with subsequent soldering in a single structure (see Fig.). Given that it requires significant mechanical strength, corrosion resistance and cleanliness, it is desirable to use the solder type PSR-45. Its composition is: copper 30%, silver 45%, zinc — 25% . Melts PSR-45 at a temperature of 730° C. is acceptable can also be solders with lower silver content (and thus more copper). For Example, AKP-25.
