Superior blade design offers easy hand operated penetration, even in hard soils. Sharp blade produces smooth, well-formed core. Nonremovable blade stays sharp--there's no need to bother with stripped threads typical of removable tips. Choose from wet/dry or zero contamination sampling tubes. Tubes are made of easy to clean nickel-plated carbon steel.
