  Stripped envelope supernovae are a sub-class of core collapse supernovae
showing several stages of H/He shell stripping that determines the class:
H-free/He-poor SNe are classified as Type Ic, H-poor/He-rich are Type Ib, and
H/He-rich are Type IIb. Stripping H/He with only stellar wind requires
significantly higher mass loss rates than observed while binary-involved mass
transfer may usually not strip enough to produce H/He free SNe. Type Ib/c SNe
are sometimes found to include weak H/He transient lines as a product of a
trace amount of H/He left over from stripping processes. The extent and mass of
the H/He required to produce these lines is not well known. In this work, a 22
M$_{\odot}$ progenitor model is stripped of the H/He shells in five steps prior
to collapse and then exploded at four explosion energies. Requiring both
optical and NIR He I lines for helium identification does not allow much He
mass to be hidden in SE--SNE. Increasing the mass of He above the CO core
delays the visibility of O I 7774 in early spectra. Our SN Ib-like models are
capable of reproducing the spectral evolution of a set of observed SNe with
reasonable estimated $E_\mathrm{k}$ accuracy. Our SN\,IIb-like models can
partially reproduce low energy observed SN IIb, but we find no observed
comparison for the SN IIb-like models with high $E_\mathrm{k}$.
