I use the "HSM cutting block special oil bottle 250 ml" for the cutting of my "HSM Shredders shredstar X6pro" oiled regularly. Just a trace of oil over the entire length slide in the paper drawer, and then snip to pieces a few leaves. Is cheaper and far more productive than the purchasing childrens' oil-soaked A4 sheets! And most importantly, it protects and maintains the cutting unit.
