A Canadian company is starting to get some mention when asked for chopping block/cutting board recommendations. How is "Larch Wood" on sharp knives. Is it too hard? I know teak is. As much as i like teak (e.g. patio furniture). The Boardsmith International FAQ says that a rating of over 1600 is too hard. Teak happens to be one of those woods. Don't know about "Larch wood". Never heard of it before i began looking into buying a quality end-grain board.
